Playing without an account: your progress is stored only in your browser (localStorage). Nothing is sent anywhere.
Cloud saves (optional): if you choose "Sign in with Google", the game uses Google Firebase to sign you in and stores one record for your account containing: your game save, the time it was saved, the game version, a random device ID, and your Google display name and profile picture URL (shown in the game). Your email address is not stored by the game.
This data is used only to back up and restore your progress. It is not sold, shared or used for advertising. Only you can read your save: access is restricted to your signed-in account.
Deleting your data: in the game, open Settings → Delete cloud save. This removes your cloud record immediately. You can also remove the game's access from your Google account at myaccount.google.com/permissions.
