Using AiChess
The service lets you play, review and study chess. Currently offered features do not involve purchases or subscriptions. Online features require an internet connection and an available server. Uninterrupted availability is not guaranteed; maintenance and network problems may interrupt access.
Accounts
Keep your password and recovery code safe. Do not impersonate others or share credentials. Usernames are visible in games and leaderboards: avoid private information or offensive content. Registering from a guest session preserves its data; signing in to an existing account does not automatically merge different histories.
Rules and fair play
Do not use engines or external assistance in human games. The server determines legality, time, results and scores under AiChess rules. Elo starts at 1400 per category and is separate from exercise scores and any FIDE rating. Leaving a page does not stop the clock. Do not knowingly submit false reports or manipulate games and leaderboards.
Content and limits
Accuracy, evaluations and explanations are learning tools affected by analysis limits. The catalog contains the stated lines, not every possible continuation. Component and data licenses are listed on the Licenses page; AiChess does not claim authorship of Stockfish or the CC0 opening catalog.
Support and data
Stop using the service or delete your account from Profile. Contact the address above for support, disputes or personal data requests. Mandatory legal protections apply and are not restricted by these terms.
