1. Acceptance of Terms

By accessing, downloading, installing, or using any part of InkRider's website, Word add-in, APIs, or related services (collectively, the "Service"), you agree to be bound by these Terms of Service ("Terms"). These Terms constitute a legally binding agreement between you ("User" or "you") and Inkansen s.r.o., a private limited liability company incorporated under the laws of the Czech Republic, with its registered office at Osadní 932/38, 170 00 Praha 7, Czech Republic, and Business Identification Number (IČO): [IČO NUMBER] (referred to in these Terms as "InkRider", "we", "us", or "our").

If you are accepting these Terms on behalf of a company or other legal entity, you represent and warrant that you have the authority to bind that entity to these Terms. In that case, "you" and "your" will refer to that entity.

If you do not agree with any part of these Terms, you must not access or use the Service. Your continued use of the Service following any updates to these Terms constitutes acceptance of the revised Terms.

2. Eligibility

You must be at least 18 years of age to use the Service. By using the Service, you represent and warrant that you meet this age requirement. The Service is not available to individuals under the age of 18.

You must have the legal capacity to enter into binding contracts under the laws of your jurisdiction. If you are using the Service on behalf of a business or other organization, you represent and warrant that you are authorized to bind that entity to these Terms.

The Service is not available to persons or entities located in countries subject to comprehensive trade sanctions administered by the U.S. Office of Foreign Assets Control (OFAC), the UK Office of Financial Sanctions Implementation, or the European Union, or to persons appearing on applicable denied-party lists. By using the Service, you represent and warrant that neither you nor any organization you represent is subject to such restrictions.

3. Description of Service

InkRider provides a Microsoft Word add-in and companion web application that enables users to generate document content using Python code and markdown within Word. The Service includes the Word add-in, the account management website, documentation, and support resources.

Some features of the Service are provided through or depend on third-party providers for functions including authentication, hosting and content delivery, and payment processing. The merchant of record for all purchases is Lemon Squeezy; by completing a purchase you also enter a payment agreement with Lemon Squeezy and their terms apply to that transaction. Your use of any third-party service integrated with or required by the Service may be subject to that provider's own terms and privacy policies.

InkRider is designed for use with Microsoft 365 versions of Word on Windows, Mac, and the web. Compatibility with specific versions, operating systems, or configurations is not guaranteed, and InkRider makes no representation that the Service will function on any particular configuration.

4. User Accounts

To access the full features of the Service, you must create an account. When registering, you agree to provide accurate, current, and complete information and to keep that information updated. InkRider reserves the right to suspend or terminate accounts with inaccurate or fraudulent registration information.

You are solely responsible for maintaining the confidentiality of your account credentials, including your password, and for all activities that occur under your account. You agree not to share your credentials with any third party, use another person's account without authorization, or transfer your account to any other person or entity. You also agree not to permit any other person to use your account by any means, whether or not you disclose your password, including shared password managers, delegated login, remote desktop access, or screen sharing used to provide concurrent access.

License scope by plan: Basic and Pro subscriptions are licensed to one individual user each. You may sign in on your own devices for your own work, but you may not permit any other person to use your account. Team and Enterprise plans provide multiple seats through separate user accounts assigned to authorized individuals; central billing or a single purchaser does not permit sharing one login among multiple users, and seat limits apply as described on the Pricing page or in your order.

If you become aware of any unauthorized access to or use of your account, or any other breach of security, you must notify us immediately at support@inkrider.com. InkRider will not be liable for any loss or damage arising from unauthorized use of your account that occurs before your notification to us.

InkRider reserves the right to require you to change your account credentials, restrict add-in access, or suspend your account if we reasonably believe your credentials have been compromised, your account is being shared or used concurrently in violation of these Terms, or your account is otherwise being used in violation of these Terms. See also Section 14 (Termination).

5. Subscriptions, Billing, and Payment

InkRider offers subscription plans as described on the Pricing page. Paid subscriptions renew automatically at the end of each billing period unless cancelled before the renewal date.

All payment transactions are processed by Lemon Squeezy, who acts as the merchant of record for InkRider subscriptions. Lemon Squeezy is responsible for payment processing, tax collection and remittance, invoicing, renewal billing, and billing support. By completing a purchase you enter into a payment agreement with Lemon Squeezy directly and agree to their applicable terms and policies. InkRider's role under these Terms is limited to providing you with access to the Service in accordance with your active subscription tier. If a payment fails or is reversed, InkRider may suspend access to paid features until the matter is resolved with Lemon Squeezy.

Subscription prices shown on the InkRider website are exclusive of applicable VAT and similar indirect taxes, which are calculated and collected by Lemon Squeezy at checkout based on your billing location and shown to you before you confirm your purchase.

We reserve the right to change subscription prices. For any price increase affecting an active subscription, we will give you at least 30 days' prior notice by email or via a prominent notice in your account. Price changes take effect at the start of the next billing period following the notice period. If you do not agree to a price change, you may cancel your subscription before the change takes effect.

6. Refunds and Cancellations

You may cancel your subscription at any time through the billing portal accessible from your account page, or by contacting us at support@inkrider.com. Upon cancellation, your subscription remains active until the end of the current paid billing period and will not renew after that date.

Because Lemon Squeezy is the merchant of record, all billing transactions, including refund requests, are processed through Lemon Squeezy's systems and policies. For any billing question or refund request, contact support@inkrider.com and we will liaise with Lemon Squeezy on your behalf, or you may contact Lemon Squeezy's customer support directly through the billing portal. Statutory rights under the consumer protection laws of your jurisdiction are not excluded by any limitation in this section.

If you are a consumer in the European Union, you have a statutory 14-day right of withdrawal from a new subscription contract under the EU Consumer Rights Directive (2011/83/EU). This right is extinguished once performance of the Service begins, provided you have been clearly informed and have given your explicit consent to immediate commencement at the time of purchase (as prompted during checkout). If that consent was not properly obtained, you retain the right and may exercise it within 14 days by contacting support@inkrider.com.

Users on the free Basic plan are not charged and may close their account at any time.

7. Acceptable Use

You agree to use the Service only for lawful purposes and in accordance with these Terms and all applicable local, national, and international laws and regulations.

The Basic (free) plan is intended for individual evaluation and personal, non-commercial use of the core workflow. If InkRider becomes part of regular commercial work, including producing deliverables for clients, use within a business context, or contributing to revenue-generating activities, you must upgrade to an appropriate paid plan. Using the free plan for commercial purposes without upgrading is a material breach of these Terms.

You are responsible for all content you create, upload, or generate using the Service, including Python code executed within the add-in and any output inserted into Word documents. You agree that such content complies with applicable laws and does not infringe the rights of any third party.

8. Prohibited Activities

You must not use the Service to:

• Use a personal-plan account (Basic or Pro) to provide access to multiple users, or otherwise share account access in breach of Section 4; • Violate any applicable local, state, national, or international law or regulation; • Infringe or misappropriate any intellectual property rights, including patents, copyrights, trademarks, or trade secrets of any party; • Upload, transmit, or otherwise make available content that is unlawful, harmful, threatening, abusive, harassing, tortious, defamatory, obscene, or otherwise objectionable; • Transmit malware, ransomware, spyware, viruses, Trojan horses, or any other malicious code or software designed to disrupt, damage, or gain unauthorized access to any system; • Attempt to gain unauthorized access to any part of the Service, other user accounts, or systems or networks connected to the Service; • Reverse engineer, decompile, disassemble, or otherwise attempt to discover the source code or underlying algorithms of any part of the Service, except as permitted by applicable law; • Use automated means, including bots, scrapers, or crawlers, to access, scrape, or interact with the Service in a manner that imposes an unreasonable or disproportionate load on our infrastructure; • Impersonate InkRider, its employees, or any other person or entity, or misrepresent your affiliation with any person or entity; • Sell, resell, sublicense, or otherwise commercialize access to the Service in a manner not expressly authorized in writing by InkRider; • Circumvent or attempt to circumvent any access controls, authentication mechanisms, usage limits, or other security measures of the Service; • Collect or harvest any personal data of other users of the Service without their consent; • Use the Service in any way that could damage, disable, overburden, or impair the Service or the servers and networks through which it is delivered.

9. Intellectual Property Rights

The Service, including all software, interfaces, content, graphics, logos, trade names, and the selection and arrangement thereof, is protected by copyright, trademark, trade secret, and other intellectual property laws. InkRider and its licensors retain all right, title, and interest in and to the Service and all improvements, modifications, and derivative works thereof.

Subject to your compliance with these Terms and payment of applicable fees, InkRider grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service solely for your own personal or internal business purposes, consistent with the scope of your subscription plan.

You may not copy, reproduce, distribute, publish, display, transmit, rent, lease, or create derivative works from any part of the Service, or reverse engineer, decompile, or disassemble any part of the Service, except as expressly permitted by applicable law or authorized in writing by InkRider.

Any feedback, suggestions, ideas, or other communications you provide regarding the Service are given voluntarily. InkRider may use such feedback without restriction, compensation, or attribution.

10. Software License Terms (End-User License Agreement or EULA)

InkRider grants you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the InkRider Word add-in (the "Add-in") on your authorised devices and Microsoft Word installations, subject to your compliance with these Terms and, for paid features, payment of applicable subscription fees. This licence is for your own internal use and does not include any right to: (a) distribute, sublicense, sell, resell, or otherwise transfer the Add-in or any copy thereof to any third party; (b) copy or reproduce the Add-in except as reasonably necessary for normal installation or backup purposes; (c) reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, object code, or underlying structure of any part of the Add-in or Service, except to the extent that applicable mandatory law expressly permits this and cannot be overridden by contract; or (d) modify, translate, adapt, or create derivative works based on the Add-in.

The Add-in includes components that execute entirely within your local browser environment, including a Python runtime (Pyodide), notebook kernel runtime (JupyterLite), and a service worker for offline functionality (collectively, "Local Components"). These Local Components are licensed to you solely as an integrated part of the Service under these Terms; they are not distributed as standalone software and you do not acquire any right to redistribute or deploy them independently of the Service.

This software licence commences upon your acceptance of these Terms and your first installation or use of the Add-in. It terminates automatically upon expiry or cancellation of your subscription (for paid plans), upon termination of these Terms for any reason, or upon InkRider's discontinuation of the Add-in. Upon termination you must cease all use of the Add-in. Closing your account requires following the account deletion process described in these Terms; uninstalling the Add-in from Word alone does not close your account.

InkRider may issue updates to the Add-in from time to time. Updates distributed via Microsoft AppSource are governed by Microsoft's standard add-in deployment mechanism. Any updates provided directly by InkRider form part of the Add-in and are subject to these Terms unless a separate licence accompanies the update.

11. User Content, Code, and Document Responsibility

You retain ownership of any Python code, scripts, document content, or other materials you create, upload, or generate using the Service ("User Content"). By using the Service, you grant InkRider a limited, non-exclusive, royalty-free license to process, store, and use your User Content solely to the extent necessary to operate and provide the Service to you.

You represent and warrant that: (a) you own or have sufficient rights to your User Content to grant the license above; (b) your User Content does not infringe any third-party intellectual property rights; and (c) your User Content does not violate any applicable law or these Terms.

Code executed within the InkRider add-in runs in a browser-based Python environment. InkRider does not claim ownership of documents you create or code you write. InkRider is not responsible for the accuracy, legality, quality, or appropriateness of code you execute or output you generate and insert into documents.

The InkRider add-in operates by writing content directly into Microsoft Word documents using the Office.js API. You are solely responsible for maintaining adequate and current backups of any Word documents on which you use the Service. InkRider strongly recommends saving a copy of any document before running InkRider operations on it. InkRider is not responsible for any loss, corruption, alteration, or unintended modification of document content arising from use of the Service, including as a result of Office.js API behaviour, unexpected interactions with content already in the document, or any failure, interruption, or error in the Service.

12. Third-Party Services

The Service depends on third-party providers for functions including cloud infrastructure, authentication, hosting and content delivery, and payment processing. These providers may change over time; our current data sub-processors are identified in the Privacy Policy. Your use of the Service may require you to accept certain third-party terms, for example, Microsoft's terms for the Office Add-in platform, or Lemon Squeezy's payment terms when making a purchase.

InkRider is not responsible for the availability, accuracy, content, policies, or practices of any third-party service, even if linked to or integrated with the Service. References to third-party services do not constitute endorsements.

If a third-party service we depend on becomes unavailable, restricts access, or changes its terms in a way that materially affects our ability to deliver features, InkRider may modify, suspend, or discontinue those features without liability to you, subject to any rights you have under applicable consumer protection law.

13. Service Availability and Modifications

InkRider provides the Service on an "as available" basis and does not guarantee any specific level of uptime, availability, or performance. We may perform maintenance, apply updates, or make changes to the Service that result in temporary unavailability, with or without prior notice where operationally feasible.

We reserve the right to modify, enhance, limit, or discontinue any feature, plan, or pricing at any time. Where material changes affect paid subscriptions, we will provide reasonable advance notice. If we discontinue the entire Service, we will provide at least 30 days' notice to paid subscribers where reasonably practicable and will offer a pro-rata refund for any unexpired prepaid subscription period.

InkRider does not guarantee that features available at the time of your subscription will remain available throughout the subscription term, including features that rely on third-party services, platform capabilities, or regulatory permissions. Features included in the free Basic plan may be added, changed, restricted, or removed at any time and without prior notice. The advance notice obligations described above apply only to paid subscription plans.

14. Termination

Either party may terminate the agreement formed by these Terms at any time. You may stop using the Service and close your account at any time. InkRider may suspend or terminate your account and access to the Service immediately, without prior notice or liability, if we determine that you have breached these Terms, engaged in conduct harmful to other users, third parties, or InkRider, or if required by law.

Upon termination: (a) your right to use the Service immediately ceases; (b) any outstanding charges for the current billing period remain due unless a refund applies under Section 6; (c) you remain responsible for all obligations incurred before termination. Sections that by their nature survive termination, including intellectual property, indemnification, disclaimer of warranties, limitation of liability, and governing law, will continue to apply.

15. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, INKRIDER AND ITS AFFILIATES, OFFICERS, EMPLOYEES, AGENTS, PARTNERS, AND LICENSORS EXPRESSLY DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT LIMITATION:

• Any implied warranties of merchantability, fitness for a particular purpose, title, accuracy, or non-infringement; • Any warranty that the Service will be uninterrupted, timely, secure, error-free, or free of viruses or other harmful components; • Any warranty that defects will be corrected or that the Service or servers that make it available are free of viruses or other harmful code; • Any warranty that results obtained from use of the Service will be accurate, reliable, complete, or suitable for any particular purpose.

Some jurisdictions do not allow the exclusion of certain implied warranties. To the extent such warranties cannot be excluded under applicable mandatory law, they are limited in duration to the minimum period required by that law.

16. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL INKRIDER OR ITS AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, PARTNERS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES OF ANY KIND, INCLUDING BUT NOT LIMITED TO:

• Loss of profits, revenue, data, business, goodwill, or anticipated savings; • Cost of substitute goods or services; • Damages resulting from unauthorized access to or alteration of your transmissions or data; • Damages for loss of business opportunity or business interruption;

arising out of or in any way related to your use of, or inability to use, the Service, even if InkRider has been advised of the possibility of such damages.

IN ANY CASE, INKRIDER'S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE TOTAL FEES ACTUALLY PAID BY YOU TO INKRIDER IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE CLAIM, OR (B) ONE HUNDRED EURO (EUR 100).

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, gross negligence or wilful misconduct, or any other liability that cannot be lawfully excluded or limited in your jurisdiction. If you are a consumer in the EU or UK, nothing in these Terms affects your statutory rights under applicable consumer protection law.

17. Indemnification

You agree to defend, indemnify, and hold harmless InkRider and its affiliates, officers, directors, employees, contractors, agents, licensors, and suppliers from and against any and all claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable legal fees) arising out of or relating to:

• Your violation of any provision of these Terms; • Your User Content; • Your use of the Service in violation of applicable laws or the rights of any third party; • Your negligent, reckless, or wilfully wrongful acts or omissions.

InkRider reserves the right to assume the exclusive defense and control of any matter subject to indemnification by you, at your expense, in which case you agree to cooperate fully. You will not settle any such claim without InkRider's prior written consent.

18. Governing Law and Jurisdiction

These Terms and any dispute arising out of or in connection with them or the Service will be governed by and construed in accordance with the laws of the Czech Republic, without regard to its conflict of law principles.

Subject to the dispute resolution provisions below, you agree to submit to the exclusive jurisdiction of the competent courts of Prague, Czech Republic for the resolution of any disputes not subject to arbitration.

If you are a consumer resident in a European Union member state, you may also have the right to bring proceedings in the courts of your country of domicile, as provided by applicable mandatory consumer protection laws. Nothing in these Terms limits rights you have under mandatory consumer protection laws in your jurisdiction.

19. Dispute Resolution

We encourage you to contact us at support@inkrider.com before initiating any formal legal proceeding. Many concerns can be resolved quickly and informally.

If informal resolution is not achieved within 30 days of written notice describing the dispute in reasonable detail, either party may pursue the claim through binding individual arbitration conducted under the rules of the Czech Arbitration Court (Rozhodčí soud při HK ČR) or another mutually agreed recognized arbitration institution. Arbitration will be conducted in English. Each party bears its own attorneys' fees and costs except where applicable law requires otherwise or the arbitrator finds in favor of a consumer claim as permitted.

YOU AND INKRIDER EACH AGREE THAT CLAIMS WILL BE BROUGHT ONLY ON AN INDIVIDUAL BASIS, AND NOT AS A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW. IF FOR ANY REASON A CLAIM PROCEEDS IN COURT RATHER THAN ARBITRATION, IN JURISDICTIONS THAT PROVIDE FOR CIVIL JURY TRIALS, EACH PARTY WAIVES ANY RIGHT TO A JURY TRIAL TO THE FULLEST EXTENT PERMITTED BY LAW.

Nothing in this section prevents either party from seeking urgent injunctive or other equitable relief from a court of competent jurisdiction to prevent irreparable harm pending the outcome of arbitration.

Notwithstanding the arbitration and class action waiver provisions above, if you are a consumer resident in the European Union or Czech Republic, those provisions do not apply to you to the extent they are unenforceable under mandatory consumer protection law (including EU Directive 93/13/EEC on unfair contract terms). You retain the right to bring disputes before competent courts. For consumer disputes in the Czech Republic, the Czech Trade Inspection Authority (Česká obchodní inspekce, www.coi.cz) provides out-of-court ADR services. EU consumers may also use the European Online Dispute Resolution (ODR) platform at https://ec.europa.eu/consumers/odr as an alternative means of resolving disputes.

20. Export Controls and Sanctions

InkRider is established in the European Union and complies with EU restrictive measures adopted under the Common Foreign and Security Policy, EU dual-use export controls (including Regulation (EU) 2021/821), UN Security Council sanctions, and applicable Czech national law.

You agree to use the Service in compliance with all export control and sanctions laws that apply in your jurisdiction, which may include, depending on where you are located or operate, EU restrictive measures, UK financial sanctions, and US Export Administration Regulations (EAR) or OFAC financial sanctions programs.

You represent and warrant that: (a) your use of the Service does not violate any applicable export control or sanctions obligation; (b) you are not subject to comprehensive trade or financial sanctions under applicable EU, UN, UK, or US measures; and (c) you do not appear on any applicable restricted-party list, including the EU Consolidated Sanctions List or the OFAC Specially Designated Nationals list.

21. General Provisions

Severability: If any provision of these Terms is held by a court of competent jurisdiction to be invalid, illegal, or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or if modification is not possible, severed from these Terms without affecting the validity and enforceability of the remaining provisions.

Waiver: No failure or delay by InkRider in exercising any right or remedy under these Terms will constitute a waiver of that right or remedy. A waiver of any breach will not constitute a waiver of any subsequent breach.

Entire Agreement: These Terms, together with InkRider's Privacy Policy and Cookie Policy, constitute the entire agreement between you and InkRider regarding the Service and supersede all prior and contemporaneous agreements, negotiations, and understandings, whether written or oral, relating to the Service.

Assignment: You may not assign, delegate, or transfer these Terms or any rights or obligations hereunder without InkRider's prior written consent. InkRider may assign these Terms in connection with a merger, acquisition, reorganization, insolvency proceeding, or sale of all or substantially all of its assets or equity, without your consent. Any attempted assignment in violation of this provision is null and void.

Force Majeure: InkRider will not be in breach of these Terms or liable for any failure or delay in performance to the extent caused by circumstances beyond our reasonable control, including acts of God, natural disasters, pandemic, war, terrorism, riots, government actions, infrastructure failures, or third-party service provider outages.

Relationship of the Parties: Nothing in these Terms creates a partnership, joint venture, franchise, employment, or agency relationship between you and InkRider. Neither party has authority to bind the other.

22. Changes to These Terms

InkRider reserves the right to update or modify these Terms at any time. When we make material changes, we will post the updated Terms on this page, update the "Last updated" date, and where required by law or where reasonably practicable, send notice to your registered email address at least 30 days before the changes take effect.

Your continued use of the Service after the effective date of any revised Terms constitutes your acceptance of those changes. If you do not agree to the revised Terms, you must discontinue use of the Service and may cancel your subscription before the effective date.
