Terms of use & disclaimer

These terms describe the rules for using ChessAthletes, its chess-training tools, login/accounts, and the subscription system. This is a legal agreement between you and the person operating ChessAthletes.

1. Who we are

ChessAthletes is an independent project operated by a single developer based in Sweden. When we say “we” or “us”, we refer to that person. When we say “you”, we mean anyone who visits the website or uses the trainers.

2. What ChessAthletes is (and is not)

ChessAthletes provides browser-based chess training tools and educational material (trainers, drills, memory tools, and related content) for practice, learning, and personal improvement.

ChessAthletes does not provide:

• professional financial advice,
• legal or medical advice,
• guarantees of rating improvement or performance outcomes,
• any form of formal chess certification.

You are responsible for how you use the tools and for any decisions or outcomes related to training or gameplay.

3. Accounts & login

ChessAthletes may offer optional login (for example via email magic links or Google sign-in) using a third-party authentication provider (currently Supabase).

• You are responsible for maintaining the confidentiality of your account access.
• You agree not to share or sell account access.
• We may suspend or restrict accounts in cases of abuse or fraud.

By creating an account or using account-based features, you agree that ChessAthletes may send service-related communications necessary to operate the service. These may include account notifications, security messages, subscription or billing confirmations, and notices about included usage or availability.

ChessAthletes does not send marketing or promotional emails unless you have explicitly opted in.

4. No warranty

ChessAthletes is provided on an “as is” and “as available” basis. We do not guarantee that:

• the trainers will always work without errors,
• the site will operate without downtime,
• the tools will meet your specific goals or expectations.

To the fullest extent permitted by law, we disclaim all implied warranties, including merchantability and fitness for a particular purpose.

5. Limitation of liability

As far as the law allows, we are not liable for any indirect or consequential damages arising from your use of ChessAthletes. This includes, but is not limited to:

• loss of training progress,
• data loss (for example, if browser storage is cleared),
• rating changes or game outcomes,
• downtime, bugs, or tool malfunctions.

Your sole remedy if you are unhappy with ChessAthletes is to stop using it and, if applicable, cancel your subscription.

6. Fair use, limits & acceptable behaviour

To keep ChessAthletes stable and prevent abuse, usage limits may apply for free users. These limits may apply in normal browsing and private/incognito mode.

To enforce fair access and prevent abuse, the system may temporarily store/process:

• a random anonymous browser identifier,
• trainer usage counters (for example, free-time usage),
• a hashed, obscured version of your IP address for anti-abuse purposes.

This information is used only to maintain fair access and expires automatically where possible. It is not used for advertising or tracking across other websites.

You agree not to:

• interfere with login or site security,
• misuse or overload the site (including automated scraping or abuse),
• copy, resell, or exploit the trainers in a harmful way.

Access may be temporarily restricted in cases of abuse or repeated limit-evasion attempts.

7. Free access

All trainers are free to use without subscriptions or monthly time limits. Account login remains available.

If you previously subscribed, use the billing management page to manage or cancel your existing subscription.

8. Intellectual property

The design, branding, and code of ChessAthletes are owned by the creator. You may not copy, resell, or host a competing service using cloned versions of ChessAthletes unless expressly permitted or released under an open-source licence.

You retain ownership of any content you input into the trainers. However, you grant us permission to process that content locally in your browser as required to provide the tool.

9. Third-party services

ChessAthletes relies on third-party providers such as:

• Cloudflare (hosting and infrastructure),
• Supabase (authentication and account management),
• Stripe (payment processing).

Your use of these services is subject to their respective policies. We are not responsible for outages or errors caused by third-party providers.

10. Changes to the service

ChessAthletes is an evolving project. We may:

• add or remove training tools,
• adjust free-tier limits,
• modify subscription tiers, pricing, or features.

Continued use of the website after updates means you accept the latest version of these terms.

11. Governing law

These terms are governed by Swedish law. Any disputes should ideally be resolved informally first. If needed, disputes will be handled in Swedish courts.

12. Contact

If you have questions, you can contact:

• Email: contact@chessathletes.com

Last updated: 2025-12-22. These terms may be updated over time. Continued use of the site means you accept the latest version.
