Terms of Service

Last Updated: March 2026

Welcome to Chessions! By accessing this website (chessions.com), we assume you accept these terms and conditions. Do not continue to use Chessions if you do not agree to take all of the terms and conditions stated on this page.

1. Services Provided

Chessions provides digital tools for chess analysis, including an Image to FEN converter utilizing custom trained machine learning models, and game analysis tools utilizing the Stockfish chess engine. These services are provided on an "as is" and "as available" basis.

2. Fair Use and Abuse

Our analysis server processing capacity is shared among all users. You agree to use the services reasonably. Automated scraping, malicious botting, or attempting to overload our backend servers with excessive game evaluation requests is strictly prohibited and may result in an IP ban or account suspension without prior notice.

3. Third-Party Integrations

To improve your experience, Chessions features integrations with popular platforms such as Chess.com and Lichess. By using features like "Sync Recent Games" or "Import from Chess.com", you agree to abide by the respective Terms of Service of those third parties. We are not responsible for the availability or accuracy of data provided by their APIs.

Users participating in online play on external platforms must adhere to the Fair Play policies of their respective servers. Chessions is strictly an after-game analysis and educational tool. Do not use its analysis engines to gain an unfair advantage in live, rated games.

4. User Accounts

You may choose to create an account via Google OAuth to save your data permanently, including PGN history and FEN positions. You are responsible for maintaining the confidentiality of your account information. We reserve the right to terminate accounts that violate our policies or remain inactive for extended periods.

5. Disclaimer of Warranties

We do not guarantee that the provided analysis (such as Brilliant moves or Blunders detection) is universally accurate for every chess variant or position. Stockfish output interpretation is automated and acts as guidance, not an absolute truth. Similarly, our Image to FEN detection may occasionally omit pieces or misinterpret low-quality images.

6. Changes to Terms

We reserve the right to modify these Terms of Service at any time. We will indicate at the top of this page the date the terms were last revised. Your continued use of the website following any changes signifies your acceptance of the updated terms.
