General Terms and Conditions (GTC)

As of: 11 October 2026

This version applies to orders placed on or after the date stated above. Contracts concluded before that date are governed by the version transmitted to the Customer when the contract was concluded.

Section 1 – Scope and Provider

(1) These General Terms and Conditions (hereinafter “GTC”) apply to all contracts concluded via the online store at store.juergenkoller.software (hereinafter “Store”) between

Jürgen Koller Software GmbH
Wilhelmstr. 5
74072 Heilbronn
Germany
Email: info@juergenkoller.software
Email for withdrawal declarations and complaints: support@juergenkoller.software
Phone: +49 7131 9244166
Commercial Register: HRB 765195, Stuttgart District Court
Managing Director: Jürgen Koller

(hereinafter “Provider”) and the customer (hereinafter “Customer”).

(2) These GTC apply to both consumers and business customers, unless expressly stated otherwise. A consumer within the meaning of Section 13 of the German Civil Code (BGB) is any natural person who enters into a legal transaction for purposes that are predominantly neither attributable to their commercial nor their independent professional activity.

(3) Deviating or supplementary terms and conditions of the Customer shall not become part of the contract unless the Provider expressly agrees to their validity in writing.

(4) The terms of use displayed within the respective App govern exclusively the use of the software. The acquisition of the App is governed exclusively by these GTC, or, where the App is acquired via the Mac App Store, by Apple’s terms. Insofar as the in-app terms of use contain provisions on acquisition, on the right of withdrawal, on liability for defects or on pricing, these GTC shall prevail.

(5) The Customer may address complaints to support@juergenkoller.software or to the postal address stated in paragraph 1. The Provider confirms receipt of a complaint within five working days and answers it without undue delay.

Section 2 – Subject Matter

(1) The subject matter of contracts concluded via the Store is the provision of digital products within the meaning of Sections 327 et seq. BGB, in particular software applications (hereinafter “Apps”) for the macOS and iOS operating systems, as well as Business Support under paragraph 6, a service.

(2) The Store offers both free and paid Apps. The essential characteristics, the functionality including any applicable technical protection measures, and the system requirements (compatibility and interoperability) of each App are set out in the product description in the Store. Technical protection measures that restrict the use of the App are additionally described in Section 7.

(3) Where an App is acquired via the Apple App Store or the Mac App Store, the contract of sale for the App is concluded not with the Provider but with Apple. That acquisition is governed exclusively by Apple’s terms; Apple handles payment, receipt and refunds. These GTC do not apply to acquisitions via the Apple App Store. The Provider’s obligations as the producer of the digital product remain unaffected.

(4) For paid Apps, the Provider may offer a free trial version. The trial phase is divided into a first stage, which may be used without providing any personal data, and a second stage, for which the Customer requests a trial licence key and provides an email address for that purpose. The duration of both stages is set out in the product description. For FreezeText and Inkra it is five days without registration and a further 14 days with a trial licence key in each case. During the second stage of the Inkra trial phase, the features of Inkra Pro are also available, including Inkra KI with a usage allowance of 50,000 tokens per calendar month; Inkra KI is not available in the first stage. These periods form part of the contract; the Provider may not shorten them retroactively for trial phases that have already begun. There is no trial phase under this paragraph for Nemeton Cloud (Section 6a(1a)); it can only be tried out with a promotion code under Section 4(6) or, by arrangement, on a demo request to the Provider.

(5) For individual Apps (currently Distill), the Provider offers AI credits. One credit entitles the Customer to use an AI function operated by the Provider once; for Distill, this is one file name suggestion via “Distill Cloud”. AI credits are a digital service within the meaning of Section 327(2) sentence 2 BGB. Like any other product, they are purchased via the order summary in the Store (Section 3); for a purchase via the Mac App Store, paragraph 3 applies. Details are governed by Section 6b.

(6) For PDF Content Search, the Provider additionally offers personal Business Support as a subscription under Section 6a(1b). Business Support is a service and not a digital product; Sections 5, 6, 7 and 9a do not apply to it, and Section 9(8) governs the Customer’s rights. There is no trial period under paragraph 4 for it.

Section 3 – Conclusion of Contract

(1) The presentation of Apps in the Store does not constitute a binding offer but an invitation to submit an offer (invitatio ad offerendum).

(2) Paid Apps and Business Support: The ordering process is completed on an order summary page in the Store. Immediately above the order button, the Customer is shown, in a clear, comprehensible and prominent manner, the essential characteristics of the App or of Business Support, the total price including value-added tax and any further costs. By clicking the “Order with obligation to pay” button, the Customer submits a binding offer to purchase. The contract is concluded when the Provider accepts the offer; acceptance is effected by the collection of the payment. The contract is therefore concluded once the payment process has been completed successfully; the confirmation under paragraph 8 documents the conclusion of the contract and is not itself the acceptance. If the Customer abandons the payment process, no contract is concluded. The processing of the payment by the payment service provider does not form part of the submission of the order.

(3) Free Apps: For free Apps, the usage contract is concluded upon download or redirection to the Apple App Store.

(4) Registration: Where registration for a user account is required, a usage contract for the account functions is concluded upon completion of registration. The Customer is obligated to provide truthful information and to keep their access credentials confidential.

(5) The Provider stores the contract text, including the declarations made by the Customer when placing the order, and transmits it to the Customer without undue delay after conclusion of the contract, together with the statutory mandatory information, by email on a durable medium. The contract text consists of the order data, these GTC in the version applicable when the contract was concluded, the withdrawal policy and the separate declarations made by the Customer during the ordering process. Customers with a user account may additionally retrieve the contract text at any time in their account under “My Orders”. Customers who have ordered as a guest may request the contract text again by quoting the order number stated in the confirmation email. The Customer may also print or electronically save the contract content before submitting the order.

(6) Technical steps for contract conclusion: The Customer may order paid Apps and Business Support in two ways.

a) Direct order: 1. clicking “Buy Now” or, for Business Support, “Subscribe to Business Support for PDF Content Search” on the product page; 2. logging in or registering (a customer account is required); 3. order summary with the information and declarations under letter c; 4. binding order by clicking “Order with obligation to pay”; 5. payment via the payment service provider under Section 4(2).

b) Order via the shopping cart: 1. clicking “Add to Cart”; 2. review of the shopping cart with the option to modify or remove products; 3. clicking “Proceed to Checkout” and logging in or registering (a customer account is required); 4. order summary with the information and declarations under letter c; 5. binding order by clicking “Order with obligation to pay”; 6. payment via the payment service provider under Section 4(2).

c) The order summary states the essential characteristics of the App, the total price including value-added tax and the email address to which the licence key will be sent or, for Nemeton Cloud and Business Support, the email address of the customer account to which the subscription is assigned, and, for AI credits, the number of credits and the device ID to which the credits will be added (Section 6b(1)). There the Customer submits, by way of separate check boxes that are not pre-ticked, the confirmation relating to these GTC and the withdrawal policy, the declarations under Section 8(3), for subscriptions under Section 8(5) or for AI credits under Section 8(6), and the separate agreement under Section 7(1), or for Business Support, in place of the agreement under Section 7(1), the separate agreement on the scope of the service under Section 6a(1b); when purchasing AI credits, the separate agreement does not apply because Section 7 does not apply to them (Section 6b(8)).

(7) Correction options: The Customer may review and correct their entries at any time before submitting the binding order. All details are summarised on the order summary page; individual details may be changed there and the order may be cancelled. Data entered may be corrected using standard keyboard and mouse functions until the ordering process is completed by clicking the “Order with obligation to pay” button.

(8) Confirmation: Without undue delay after conclusion of the contract, and in any event before the provision of the digital content or the performance of the service begins, the Provider transmits to the Customer an email on a durable medium. That single message is both the acknowledgement of receipt of the order and the confirmation of the contract; no separate acknowledgement of receipt is sent before payment, because until then no contract has been concluded. It reproduces the content of the contract. It also records that the Customer, before performance of the contract, expressly consented to the Provider beginning performance of the contract before expiry of the withdrawal period and confirmed their awareness that they thereby lose their right of withdrawal. For subscriptions, it records instead that the Customer expressly requested that the Provider begin performance before expiry of the withdrawal period and confirmed their awareness of the obligation to pay compensation under Section 8(5). For AI credits, it records instead the declaration under Section 8(6) and the device ID to which the credits were added. The separate agreement under Section 7(1) is likewise recorded, or for Business Support the agreement on the scope of the service under Section 6a(1b).

Section 4 – Prices and Payment

(1) All prices stated in the Store are total prices in euros. They include the applicable value-added tax and all other price components. The total price stated applies uniformly to all orders placed by consumers resident in the European Union. It does not change because the rate of value-added tax depends on the Customer’s residence or habitual abode; a higher or lower tax rate affects the Provider’s share of the total price only. No further costs arise. For Business Support for PDF Content Search, the price depends on the tier booked (number of the Customer’s employees, Section 6a(1b)). Traders with a valid VAT identification number from another Member State of the European Union and traders established outside the European Union pay the net price shown on the order summary for Business Support; the value-added tax is owed by the recipient of the service (reverse charge) or the transaction is not taxable in Germany. Costs charged to the Customer by the Customer’s own payment service provider, in particular fees for currency conversion or cross-border payments, do not form part of the total price and are borne by the Customer.

(2) Payment is processed via the payment service provider Stripe. The available payment methods are displayed to the Customer at the latest at the beginning of the ordering process. The Provider delivers worldwide; no delivery restrictions exist. The Provider offers Business Support for PDF Content Search to consumers only if they are resident in the European Union (Section 6a(1b)). The payment page of the payment service provider serves exclusively to process the payment; the contract with the Provider is already concluded in accordance with Section 3(2).

(3) The purchase price is due immediately upon placing the order. For subscriptions (Section 6a), the charge for the first billing period is due in advance upon placing the order and the charge for each further billing period is due in advance at the start of that period; the payment service provider collects it using the means of payment chosen when the order was placed.

(4) The Provider reserves the right to change prices for products not yet ordered at any time. For orders already placed, the price displayed at the time of the order applies.

(5) The Provider makes available to the Customer a receipt in text form for every order and transmits it by email together with the contract confirmation under Section 3(8). The invoice is attached to the contract confirmation under Section 3(8); for traders who stated a VAT identification number during the ordering process, it shows that number.

(6) A promotion code grants a one-time discount: for a one-time purchase on the purchase price, for a subscription on the charge for the first billing period. It is entered on the order summary page; the discount and the amount payable are displayed there before the order is placed. Promotion codes cannot be combined with one another and cannot be paid out in cash. For subscriptions, the regular charge applies from the second billing period onwards.

Section 5 – Provision of Digital Products

(1) The provision of digital products takes place via one of the following methods, depending on the App:

Direct download: Via a download link in the Store.
Apple App Store: Via redirection to the Apple App Store (iOS) or Mac App Store (macOS).

(2) Provision takes place without undue delay after conclusion of the contract, for paid Apps after receipt of payment, as a rule within a few minutes and no later than within 24 hours. If provision does not take place, the Customer may assert the rights under Section 327c of the German Civil Code (BGB).

(3) For Apps provided via the Apple App Store, the Provider assumes no responsibility for the availability or technical functionality of the Apple App Store.

(4) Paid Apps are provided with a licence key. The Provider transmits the licence key without undue delay after conclusion of the contract and receipt of payment by email to the address given by the Customer during the ordering process. An internet connection is required for the initial activation of the licence key on a device. The details of activation and of the recurring licence check are governed by Section 7. Nemeton Cloud is enabled for the customer account with which the Customer placed the order; the Customer does not need to enter a licence key for it (Section 6a(1a)). AI credits are added, after receipt of payment, to the credit account of the device ID shown on the order summary; there is no licence key for them (Section 6b).

Section 6 – Usage Rights and Licence

(1) Upon provision of the App, the Provider grants the Customer a simple (non-exclusive), perpetual right to use the software. For subscriptions (Section 6a), the right of use as a whole is limited to the duration of the subscription; a one-time purchase of the same App acquired alongside it remains unaffected.

(2) The right of use includes the installation and use of the App for private and commercial purposes. For licences acquired via the Store, the Customer may activate the App simultaneously on at least ten (10) devices used by the Customer. The Customer may release an activation from a device at any time and transfer it to another device; such transfer is free of charge and unlimited in number. The figure of ten devices is a minimum; the Provider may not reduce it for licences already granted. A higher number of devices that may be used simultaneously applies if it is stated expressly, separately and prominently in the product description of the App concerned; in all other respects sentence 2 applies. For licences acquired via the Mac App Store, sentence 2 does not apply; there the number of devices that may be used simultaneously is governed by Apple’s terms (Section 2(3)).

(3) The Customer is not entitled to reproduce the App (beyond its intended use), decompile, disassemble, or otherwise reverse-engineer the source code, unless expressly permitted by law (Sections 69d, 69e of the German Copyright Act).

(4) Transfer of the software to third parties is only permitted together with the complete transfer of all usage rights and the complete cessation of the Customer’s own use.

Section 6a – Subscriptions

(1) Individual products are offered as a subscription (currently Inkra Pro, Nemeton Cloud and Business Support for PDF Content Search). A subscription comprises ongoing services, in particular an AI function operated by the Provider or, for Business Support, personal support by the Provider; for Inkra Pro it combines them with the provision of the App. The scope, usage allowances, term and charge are set out in the order summary and in the contract confirmation under Section 3(8).

(1a) Nemeton Cloud. Nemeton Cloud is the AI assistant of the Nemeton App that the Provider supplies via its server. The subject matter of the subscription is this service only; the Nemeton App itself is not the subject matter of the subscription. Nemeton Cloud can only be ordered with a customer account and is assigned to that customer account; to use it, the Customer signs in to Nemeton with that customer account. The usage allowance applies per calendar month, including for the yearly subscription, and jointly for all devices on which the Customer is signed in with that customer account.

(1b) Business Support for PDF Content Search. Business Support is personal support provided by the Provider to the Customer for setting up and using PDF Content Search, by email to business@juergenkoller.software and, on request, by call-back at an agreed time. The Provider promises a first personal reply on working days (Monday to Friday, excluding public holidays in Baden-Württemberg, Germany) no later than the next working day; requests received by 4 pm German time count for the same day. What is promised is a reply with an assessment, not the resolution of a request by a particular time. During holidays or illness the first reply can take up to three working days, on no more than 30 working days per contract year; three working days are the upper limit in every case. If the Provider cannot keep this limit for more than two weeks, the Customer may terminate Business Support for good cause; the Provider refunds the charge for the period after the end of the contract proportionately. The Provider announces planned absences of more than one week in advance. Not included are custom development or adaptations, on-site visits, data recovery, support for macOS, Apple Mail or other software beyond its interaction with PDF Content Search, and availability around the clock. Business Support is provided for lawfully used copies of PDF Content Search (purchased licence, subscription in the Mac App Store or current trial period). The Provider may request proof. If proof is not provided, the Provider may defer support until proof is provided and cancel the subscription with 14 days’ notice; it refunds the charge for the period after the end of the contract proportionately. A licence for PDF Content Search is not included. Bug fixes for PDF Content Search are free of charge for all customers, with or without Business; the Customer’s rights under Section 9 remain unaffected. Business Support is offered in three tiers: for up to 10, up to 50 and up to 250 employees of the Customer (the first tier also applies to consumers and sole traders); for more than 250 employees the Provider offers Business Support on request to business@juergenkoller.software. The number of employees on the day of the order and on the day of each renewal is decisive. The Customer chooses the tier when ordering; the Provider may request proof. If the number of employees on the day of a renewal exceeds the tier booked, the applicable tier applies from that renewal at the charge stated for it; the Provider notifies the Customer of this in text form at least 30 days beforehand, and the Customer may cancel the subscription to the end of the current contract year. Growth during the contract year changes nothing until the next renewal. All employees of the Customer may submit requests, from any email address, stating the order number; there is no limit on the number of requests. The Provider offers Business Support to consumers only if they are resident in the European Union. Business Support is offered only as a yearly subscription, can only be ordered with a customer account and is assigned to that customer account; the Customer gives the separate agreement on the scope of the service during the ordering process (Section 3(6)(c)).

(2) Term and renewal. A monthly subscription has a term of one billing month and renews by a further billing month at a time unless it is cancelled. A yearly subscription has a term of one year; if it is not cancelled to the end of the first year, it continues for an indefinite period.

(3) Cancellation. The Customer may cancel a monthly subscription at any time to the end of the current billing month. The Customer may cancel a yearly subscription to the end of the first year, up to and including its last day, and thereafter at any time with one month’s notice; in that case the Provider refunds the charge already paid for the period after the end of the contract proportionately, within 14 days, to the original means of payment. The right to terminate for good cause (extraordinary termination) remains unaffected.

(4) Cancellation button. The Customer may cancel any subscription via the “Cancel contracts here” button, which is permanently available on every page of the Store (Section 312k BGB). Cancellation is also possible in text form to support@juergenkoller.software. The Provider confirms every cancellation without undue delay in text form, stating the time of receipt and the time at which the subscription ends.

(5) End of the subscription. When the subscription ends, the services under paragraph 1 end. If the Customer has also acquired the same App as a one-time purchase, the right of use under that purchase remains unaffected. When Nemeton Cloud ends, the use of the Nemeton App remains unaffected, including the use of its AI assistant with the Customer’s own API key or a local AI. The files created by the Customer remain on the Customer’s devices and remain readable. When Business Support ends, the use of PDF Content Search and general help by email to support@juergenkoller.software remain unaffected.

(6) Price changes. The Provider changes the charge for an existing subscription only with the Customer’s consent. The Provider gives notice of an intended change in text form at least 30 days before it takes effect; if the Customer does not consent, the subscription continues at the previous charge until it is cancelled.

Section 6b – AI Credits

(1) Assignment. AI credits are assigned to a pseudonymous credit account linked to the installation of the App on a device (device ID; the App shows it under Settings → AI Credits). No registration is required to use the credits; they are purchased in the Store under Section 3(6), like any Store purchase with a customer account. For this, the App passes the device ID to the order summary; with the purchase, the device ID is associated with the customer account. Credits cannot be transferred to other devices or persons; upon request to support@juergenkoller.software, the Provider transfers the remaining balance to a new device ID of the same Customer if the Customer proves the purchase.

(2) Usage. Each name suggestion via Distill Cloud uses one credit, even if the Customer does not adopt the suggestion. If processing fails for reasons for which the Provider is responsible, no credit is used. The current balance is shown in the App.

(3) No expiry. Purchased credits do not expire. They only end when the credit account is closed at the Customer’s request or when the Provider discontinues the AI function under paragraph 5.

(4) No cash payout. Credits are not paid out in cash; the Customer’s statutory rights (withdrawal, rights in case of defects, refund under paragraph 5) remain unaffected.

(5) Discontinuation. If the Provider discontinues the AI function, it announces this in the App at least three months in advance and refunds the pro-rata purchase price for paid, unused credits.

(6) Starter credits and voucher codes. Free starter credits and credits from voucher codes redeemed by the Customer in the App are granted free of charge; they are used before purchased credits and are excluded from the refund under paragraph 5 sentence 1.

(7) Purchases via Apple. For credits purchased via the Mac App Store, Apple’s terms apply exclusively to payment, withdrawal and refunds (Section 2(3)); paragraphs 1 to 6 apply accordingly to use.

(8) No licence check. Section 7 does not apply to AI credits. Distill Cloud works via the Provider’s server and requires an internet connection each time it is used (Section 9a(6)). If the server is unreachable over a longer period for reasons for which the Provider is responsible, the service is defective to that extent; the Customer’s rights under Sections 327d et seq. BGB remain unaffected.

Section 7 – Licence Verification and Device Activation

(1) Separate agreement under Section 327h of the German Civil Code (BGB). Four characteristics deviate from the objective requirements that a digital product must meet under Section 327e(3) BGB (for Inkra, Inkra Pro and Nemeton Cloud, instead, the characteristics stated on the order summary page and separately agreed during the ordering process): the number of devices that may be activated simultaneously under Section 6(2), the check over the internet under paragraph 4, the minimum version under paragraph 5 and the discontinuation of the product under paragraph 6. These characteristics apply only if the Customer was specifically informed of them before submitting their contractual declaration and if the deviation was expressly and separately agreed in the contract. Section 327h BGB permits a deviation from the objective requirements only where both of these conditions are met. This clause does not replace that separate agreement. The Provider obtains it during the ordering process by way of a separate check box that is not pre-ticked and records it in the contract confirmation under Section 3(8). If that confirmation is absent, the objective requirements apply without the restrictions referred to. Paragraph 3 does not describe a deviation but the data processing; it is not the subject matter of the separate agreement.

(2) Device activation. The licence key is activated on the Customer’s device. For activation, the App transmits the licence key, a device identifier, a designation of the device, the device type and the program version to the Provider’s licence server. The number of devices that may be activated simultaneously follows from Section 6(2).

(3) Recurring licence check and product status. After activation, the App checks the licence status at recurring intervals, as a rule when the program is started. In doing so it transmits the product identifier, the licence key and the device identifier. In addition, the App retrieves the status of the product on launch, at most once every 24 hours. Which data are transmitted in detail, and for how long they are stored, is set out in the Privacy Policy.

(4) Check over the internet. An App that you use with a licence key from our Store checks your licence over the internet. For that it needs an internet connection at least every 40 days. If the check does not take place for longer than that — for whatever reason, including our licence server being unreachable — the App restricts its functions until the next check succeeds. The extent of the restriction is stated in the order summary and in the contract confirmation of the App concerned: FreezeText, for example, switches off its capture function while your history remains readable and exportable; Inkra opens your documents read-only (paragraph 4a); other Apps are locked until the next successful check. Your files remain on your device. Your licence remains in existence and revives with the next successful check without any action on your part. We undertake to keep the 40 days and will not shorten them. If our licence server is unreachable over a longer period for reasons for which we are responsible, the App is defective to that extent; your rights under Sections 327d et seq. BGB remain unaffected. The agreement under paragraph 1 covers the way the check works, not a failure in performance on our part. If your licence ends — for example because you have withdrawn from the contract or returned the App, or because the price has been refunded or charged back — the restriction takes effect at the next check and at the latest 40 days after the licence has ended, even without an internet connection; in that case the licence does not revive. For licences acquired through the Mac App Store, paragraph 8 applies.

(4a) Inkra. For Inkra and Inkra Pro, paragraph 4 applies with the proviso that Inkra opens the Customer’s documents read-only for as long as the check does not succeed. Inkra Pro additionally checks after the end of each billing period whether the subscription exists; if that check does not succeed, the Pro features are unavailable until the next successful check. If the Customer has also bought Inkra as a one-time purchase, its use remains unaffected.

(4b) Nemeton Cloud. Paragraphs 2 to 6 and 8 do not apply to Nemeton Cloud; the Provider supplies Nemeton Cloud for the duration of the subscription (Section 9(6), fourth sentence). Nemeton Cloud is supplied via the Provider’s server and requires an internet connection and signing in with the customer account under Section 6a(1a) each time it is used; the server checks at that point whether the subscription exists. If the server is unreachable over a longer period for reasons for which the Provider is responsible, Nemeton Cloud is defective to that extent; the Customer’s rights under Sections 327d et seq. BGB remain unaffected.

(5) Minimum version. The Provider may specify a minimum version for the operation of the App in order to close security vulnerabilities. Against a licence purchased and activated by the Customer, such a specification takes effect at the earliest 30 days after the App has learned of it; within that period the App notifies the Customer of the forthcoming effect and of the successor version available. The Provider makes the successor version available free of charge; it runs on the minimum system requirement stated when the contract was concluded. In the free trial phase under Section 2(4) the specification takes effect at once.

(6) Discontinuation of the product. The Provider may discontinue the distribution and further development of the App and deactivate the product on the server side. Against a licence purchased and activated, a server-side deactivation takes effect at the earliest 30 days after the App has learned of it; paragraph 5 sentence 2 applies accordingly. The Provider informs the Customer of the discontinuation on a durable medium. If the Provider discontinues operation permanently, the Customer receives, in good time and free of charge, a version whose use no longer requires the check under paragraph 4.

(7) Updates are free of charge. Updates to the App, including the successor versions, are free of charge for the Customer. The Provider does not make continued use dependent on the acquisition of a further licence. For Inkra, sentence 1 applies to the updates within the major version purchased; the Provider may offer a new major version separately. The update obligation under Section 9(4) remains unaffected.

(8) Mac App Store. Paragraphs 3 to 6 do not apply to licences acquired through the Mac App Store. As against the holder of such a licence, the App retrieves no product status; a check under paragraph 4, a minimum version under paragraph 5 and a server-side deactivation under paragraph 6 do not take place as against them. During the free trial phase under Section 2(4), by contrast, paragraphs 3 to 6 do apply in the Mac App Store as well.

Section 8 – Right of Withdrawal

Withdrawal Policy

Right of withdrawal

You have the right to withdraw from this contract within fourteen days without giving any reason.

The withdrawal period is fourteen days from the day of the conclusion of the contract.

To exercise your right of withdrawal, you must inform us

Jürgen Koller Software GmbH
Wilhelmstr. 5
74072 Heilbronn
Germany
Phone: +49 7131 9244166
Email: support@juergenkoller.software

by means of an unequivocal statement (e.g. a letter sent by post or an email) of your decision to withdraw from this contract. You may use the attached model withdrawal form, but it is not obligatory.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we shall reimburse to you all payments received from you, including the costs of delivery (with the exception of the supplementary costs resulting from your choice of a type of delivery other than the least expensive type of standard delivery offered by us), without undue delay and in any event not later than fourteen days from the day on which we are informed about your decision to withdraw from this contract. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

If, for a subscription, you requested to begin the performance of services during the withdrawal period, you shall pay us an amount which is in proportion to what has been provided until you have communicated us your withdrawal from this contract, in comparison with the full coverage of the contract.

If, when purchasing AI credits, you requested that performance of the contract begin during the withdrawal period, you shall pay us an appropriate amount corresponding to the proportion of credits already used by the time you inform us of the exercise of the right of withdrawal in relation to the total number of credits in the package.

Premature Expiry of the Right of Withdrawal for Digital Content

(3) In the case of contracts for the supply of digital content not supplied on a tangible medium which oblige the Customer to pay a price, the right of withdrawal expires if

a) the Provider has begun to perform the contract,
b) the Customer has expressly consented to the Provider beginning performance of the contract before the expiry of the withdrawal period,
c) the Customer has confirmed their awareness that, by consenting under letter b, their right of withdrawal expires once performance of the contract begins, and
d) the Provider has provided the Customer with a confirmation of the contract in accordance with Section 312f of the German Civil Code (BGB) (Section 3(8) sentences 3 and 4)

(Section 356(6) no. 2 BGB, which sets out these four cumulative conditions for digital content). The Customer submits the declarations under letters b and c during the ordering process by way of separate check boxes that are not pre-ticked; they are recorded in the contract confirmation under Section 3(8). If any of the conditions under letters a to d is not met, the right of withdrawal does not expire prematurely.

(4) Free Apps and trial versions. If the Customer undertakes neither to pay a price nor to provide personal data, there is no right of withdrawal. If, on the other hand, the Customer provides personal data or undertakes to do so – for instance by giving an email address in order to receive a trial licence key under Section 2(4) – the Customer has a right of withdrawal. That right expires as soon as the Provider has begun to perform the contract (Section 356(6) no. 1 BGB, which governs contracts without an obligation to pay a price). The section “Withdrawal Policy” applies accordingly, with the proviso that a price is not to be reimbursed.

(5) Subscriptions. For subscriptions under Section 6a, the right of withdrawal exists in accordance with the withdrawal policy. If the Customer expressly requests that the Provider begin the ongoing services before the withdrawal period expires, the Customer owes, in the event of withdrawal, an appropriate amount as compensation corresponding to the proportion of the services provided up to the withdrawal in relation to the full scope of the agreed services. Insofar as the subscription concerns the supply of digital content (for Inkra Pro, the Inkra App), paragraph 3 applies accordingly; Nemeton Cloud and Business Support do not include the supply of digital content. For Business Support for PDF Content Search, the Provider does not claim compensation; in the event of withdrawal, it refunds the full amount. The Customer submits these declarations during the ordering process by way of separate check boxes that are not pre-ticked; they are recorded in the contract confirmation.

(6) AI credits. When purchasing AI credits (Section 6b), consumers have the right of withdrawal as set out in the withdrawal policy. If the Customer expressly requests that the Provider begin performance before the withdrawal period expires and confirms their awareness of the consequences, the following applies: if the Customer withdraws, they owe compensation for the credits used up to that point in proportion to the purchase price of the package (Section 357a(2) BGB); the right of withdrawal expires once all purchased credits have been used (Section 356(4) BGB). The Customer makes this declaration on the order summary by means of a separate check box that is not pre-ticked (Section 3(6)(c)); it is recorded in the contract confirmation under Section 3(8).

(7) Traders. The Provider grants the right of withdrawal under this Section also to Customers who are traders.

Section 9 – Warranty and Updates

(1) The statutory warranty rights pursuant to Sections 327d et seq. BGB for contracts on digital products apply.

(2) The Provider warrants that, at the time of provision, the App meets the subjective (contractually agreed) and objective (usually expected) requirements and is free from product defects. The usual characteristics also include requirements that the Customer may expect on the basis of public statements made by the Provider, in particular in advertising (Section 327e(3) sentence 2 of the German Civil Code (BGB)).

(3) Reversal of the burden of proof: If, within one year of its provision, the App shows a state that deviates from the requirements under Section 327e BGB, it is presumed that the App was already defective at the time of provision (Section 327k(1) BGB, which governs the reversal of the burden of proof; subsequent performance is governed by Section 327l BGB). The presumption does not apply if the Customer’s digital environment was not compatible with the technical requirements of the App at the relevant time; those technical requirements are set out in the product description in the Store (Section 327k(3) no. 1, (4) no. 1 BGB).

(4) Update obligation (Section 327f BGB): The Provider provides the Customer with the updates that are necessary to maintain the conformity of the App with the contract, including security updates, and informs the Customer about those updates. The relevant period is at least 36 months from provision; a longer period that the Customer may expect on the basis of the type and purpose of the App and taking into account the circumstances and the nature of the contract remains unaffected (Section 327f(1) sentence 3 no. 2 BGB). For subscriptions, the relevant period is the duration of the subscription (Section 327f(1) sentence 3 no. 1 BGB). Updates within that period are free of charge for the Customer. If the Customer fails to install an update provided within a reasonable period, the Provider is not liable for a product defect that is attributable solely to the absence of that update, provided that the Provider informed the Customer of the availability of the update and of the consequences of failing to install it, and provided that the failure to install it, or its incorrect installation, is not attributable to defective installation instructions (Section 327f(2) BGB).

(5) The warranty rights of the Customer cannot be restricted vis-à-vis consumers by GTC (Section 327s BGB).

(6) For one-time purchases, the App is provided on a single occasion; continuous provision is not owed. After activation, an App used with a licence key from the Store remains fully usable only if it can check the licence over the internet at least every 40 days; if the check does not take place, the App restricts its functions in accordance with Section 7(4) and (4a); for Nemeton Cloud, Section 7(4b) applies. This does not apply to licences acquired through the Mac App Store (Section 7(8)). For subscriptions, the Provider owes continuous provision for the duration of the subscription.

(7) Changes to the App that go beyond what is necessary to maintain conformity with the contract and that adversely affect the Customer’s access to the App or its usability are made by the Provider – even where Section 327r BGB does not apply directly to the contract – only if the Provider informs the Customer, on a durable medium and within a reasonable period before the time of the change, of the features and the time of the change. If such a change adversely affects access or usability more than merely insignificantly, the Customer may terminate the contract free of charge within 30 days of receipt of that information, unless access to, and usability of, the unchanged App remain available to the Customer at no additional cost.

(8) Business Support. Paragraphs 1 to 7 do not apply to Business Support (Section 6a(1b)). It is a service; the statutory rules on service contracts (Sections 611 et seq. BGB) apply to it. For PDF Content Search itself, the rules on the respective digital product continue to apply unchanged.

Section 9a – Features Based on Artificial Intelligence

(1) Scope. Some Apps contain features that use artificial intelligence to generate results, such as texts, translations, summaries, answers or suggested file names (hereinafter “AI Features”). Which AI Features an App has, whether they run on the Customer’s device or via a server, and whether a usage quota applies to them (such as credits or a monthly quota) is set out in the product description and the order overview.

(2) Characteristics. AI Features calculate their results on the basis of probabilities. Even when working properly, their results may therefore be incomplete, inaccurate, misleading, out of date or false, even if they are convincingly worded, and the same input may lead to different results. This reflects the state of the art and is the usual characteristic of such features. The Provider owes AI Features that work as stated in the product description; it does not owe that every individual result is correct in substance. Results of AI Features do not reflect the views of the Provider or of the respective AI provider. The Customer’s rights in the event of defects under Section 9 remain unaffected; there is a defect in particular if an AI Feature does not work as stated in the product description.

(3) Review by the Customer. Factual statements in results of AI Features should not be relied upon unless the Customer has checked them independently. The Customer therefore reviews results before using, passing on or publishing them or basing decisions on them, and decides for itself whether review by a human is necessary for its purpose. This also applies to suggestions on the basis of which the App renames, moves or changes files.

(4) No advice. Results of AI Features are not legal, tax, financial or medical advice and do not replace such advice, even where they deal with such topics.

(5) Liability. The Provider is liable for damage in connection with AI Features in accordance with Section 10; no further limitation applies. If the Customer has used a result without review contrary to paragraph 3, this is taken into account as contributory fault when assessing a claim for damages (Section 254 BGB).

(6) AI Features provided via a server. AI Features that work via a server require an internet connection. For these, the Provider uses services of AI providers, currently Anthropic and OpenAI; the data transmitted in the process is described in the Privacy Policy. The Provider may change the AI model used or the AI provider if the characteristics of the AI Feature stated in the product description are preserved; Section 9(7) remains unaffected. In the case of one-time purchases, the other functions of the App remain usable without an AI Feature provided via a server.

Section 10 – Limitation of Liability

(1) The Provider shall be liable without limitation for damages arising from injury to life, body, or health based on an intentional or negligent breach of duty by the Provider or its legal representatives or vicarious agents.

(2) The Provider shall be liable without limitation for other damages based on an intentional or grossly negligent breach of duty by the Provider or its legal representatives or vicarious agents.

(3) In the event of a slightly negligent breach of material contractual obligations (cardinal obligations), the Provider’s liability is limited to the foreseeable, contract-typical damage. Material contractual obligations are those whose fulfillment is essential for the proper performance of the contract and on whose compliance the Customer may regularly rely.

(4) Otherwise, the Provider’s liability for damages caused by slight negligence is excluded.

(5) The above limitations of liability do not apply to claims under the Product Liability Act or in the case of an assumed guarantee.

(6) The Customer’s rights in the event of product defects under Sections 327i et seq. BGB, in particular to subsequent performance, price reduction and termination of the contract, remain unaffected by the above limitations of liability. The Customer’s rights in the event of a failure to provide the App under Section 327c BGB likewise remain unaffected.

Section 11 – Data Protection

(1) For information on the processing of personal data, please refer to our Privacy Policy.

(2) The Privacy Policy provides information in particular on the processing carried out in connection with the handling of payments by the payment service provider, on the processing carried out in connection with requesting a trial version, with licence activation and with the recurring licence check under Section 7, on the processing carried out when AI Features under Section 9a are used, and on the storage of information on the Customer’s terminal equipment.

Section 12 – Final Provisions

(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). If the Customer is a consumer, the mandatory consumer protection provisions of the state in which the Customer has their habitual residence shall remain unaffected.

(2) If the Customer is a merchant, a legal entity under public law, or a special fund under public law, the place of jurisdiction is Heilbronn.

(3) The Provider is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board. The online dispute resolution platform operated by the European Commission was discontinued on 20 July 2025. The European Commission provides a directory of the consumer dispute resolution bodies in the Member States of the European Union at https://consumer-redress.ec.europa.eu/dispute-resolution-bodies.

(4) Should individual provisions of these GTC be or become invalid or unenforceable, the validity of the remaining provisions shall remain unaffected.

(5) The contract may be concluded in German or in English. The language version in which the Customer completed the ordering process is authoritative. The Provider keeps these GTC available in both language versions at juergenkoller.software/agb.html and juergenkoller.software/en/terms.html. Where the language versions diverge, the German version is authoritative for the interpretation of the withdrawal policy, because that version corresponds to the statutory model; in all other respects the language version in which the contract was concluded applies.
