Terms of Service

Super Chess Puzzle

Last updated: July 28, 2026

1. Acceptance of These Terms

These Terms of Service ("Terms") form a legal agreement between you ("you" or the "User") and Max Anton Schneider ("we", "us", "our", or the "Licensor"), the developer of the Super Chess Puzzle mobile application (the "App"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.

If you are using the App on behalf of a minor, you confirm that you have the legal authority to agree to these Terms on their behalf.

2. Description of the App

Super Chess Puzzle is a chess puzzle training application. The App works entirely offline: puzzles are bundled with the App, and your progress (rating, streak, solved-puzzle count, and preferences) is stored only on your own device. The App does not require you to create an account and does not communicate with any server operated by us.

3. License Grant

Subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, revocable, limited license to download, install, and use the App on any Apple-branded device or Android device that you own or control, solely for your own personal, non-commercial use, and in accordance with the usage rules set out in the applicable App Store's terms of service.

You may not:

• copy, modify, or create derivative works of the App, except as permitted by applicable law;
• reverse engineer, decompile, or disassemble the App, except to the extent such restriction is prohibited by applicable law;
• rent, lease, lend, sell, redistribute, or sublicense the App;
• remove or alter any proprietary notices or labels on the App.

4. Intellectual Property

The App, including its design, graphics, sound effects, puzzle presentation, and all associated intellectual property (excluding third-party open-source components, which remain governed by their own licenses), is owned by us or our licensors and is protected by copyright and other intellectual property laws. Nothing in these Terms transfers any ownership rights to you.

Chess puzzle positions are based on standard chess notation (FEN/PGN) and general chess theory, which are not subject to proprietary ownership.

5. Acceptable Use

You agree not to use the App:

• for any unlawful purpose or in violation of any applicable local, national, or international law or regulation;
• to attempt to gain unauthorized access to, interfere with, damage, or disrupt the App or the devices on which it runs;
• to circumvent, disable, or otherwise interfere with any security-related or usage-restriction features of the App.

6. In-App Purchases and Subscriptions

The current version of the App does not offer any in-app purchases, subscriptions, or advertising. If we introduce paid features in the future, they will be processed exclusively through the applicable App Store's in-app purchase system, and additional terms specific to those features will be presented to you for acceptance at that time.

7. No Warranty

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS.

In the event of any failure of the App to conform to any applicable warranty, you may notify us at the contact address below, and we will, to the extent required by applicable law, address such failure. Any other claims, losses, liabilities, damages, costs, or expenses attributable to such a failure are our sole responsibility as Licensor, to the extent required by law.

Nothing in this section limits any statutory rights you have as a consumer that cannot lawfully be excluded or limited.

8. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, RESULTING FROM YOUR USE OF OR INABILITY TO USE THE APP.

This limitation does not apply to liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under applicable law (including mandatory German law under §§ 276, 309 No. 7 BGB).

9. Product Claims and Legal Compliance

We, not Apple or Google, are solely responsible for the App and its content, for addressing any claims by you or any third party relating to the App (including product liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and consumer protection or similar claims), and for investigating, defending, settling, and discharging any claim that the App infringes a third party's intellectual property rights.

By using the App, you represent and warrant that you are not located in a country subject to a government embargo, or designated by any government as a "terrorist supporting" country, and that you are not listed on any government list of prohibited or restricted parties.

10. Third-Party App Store Terms

If you downloaded the App from Apple's App Store, you acknowledge that:

• these Terms are concluded between you and us only, and not with Apple, and Apple is not responsible for the App or its content;
• Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the App;
• Apple is not responsible for addressing any claims by you or any third party relating to the App;
• Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms and, upon your acceptance of these Terms, Apple has the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

Your use of the App must also comply with the applicable App Store's terms of service and privacy policy:

• Apple Media Services Terms and Conditions: https://www.apple.com/legal/internet-services/itunes/
• Apple Privacy Policy: https://www.apple.com/legal/privacy/
• Google Play Terms of Service: https://play.google.com/intl/en_us/about/play-terms/
• Google Privacy Policy: https://policies.google.com/privacy

11. Termination

We may suspend or terminate your license to use the App if you fail to comply with these Terms. You may stop using the App and delete it from your device at any time. Because the App stores data only locally, uninstalling it removes your locally stored data (rating, streak, and preferences); we hold no copy of it.

12. Changes to These Terms

We may update these Terms from time to time, for example to reflect new features or legal requirements. If we make material changes, we will update the "Last updated" date above and, where required by law, provide additional notice. Your continued use of the App after changes take effect constitutes acceptance of the revised Terms.

13. Governing Law and Jurisdiction

These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules and excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection afforded by mandatory provisions of the law of your country of habitual residence.

To the extent permitted by law, the exclusive place of jurisdiction for any disputes arising from or in connection with these Terms is Kempten (Allgäu), Germany. This does not apply where mandatory consumer-protection law provides for a different jurisdiction.

14. Severability

If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions will remain in full force and effect, and the invalid or unenforceable provision will be deemed modified to the minimum extent necessary to make it valid and enforceable.

15. Contact
