Game data in your browser
Local two-player and bot games save the latest game in your browser’s local storage so you can continue later on that device. While you are signed in, their moves are also saved to your account for Game history. Online play uses short-lived session storage for a new-game request ID or an invitation request. Clearing browser site data removes the local copies and may sign you out, but does not remove game records saved to your account.
