Privacy
An account stores your email, name, nickname, language, voice, and high scores on the server, with a copy of language and voice on this device. Signing out clears that device copy for the account. Guest play stays in a separate device store and is not merged into an account unless you save it yourself.
Sessions may include an IP address and browser string until the session expires. Expired sessions are deleted. Teacher lines, spoken audio, and scoresheet images you submit are sent to xAI to produce the lesson. They are not placed on the public high-score list.
High scores show a nickname to signed-in players with a verified email. The email behind a nickname is returned only to an admin, one row at a time, and each reveal is stored with the admin, the address, the row, and the time.
