On this device: carrots, unlocks, achievements, settings and your run history are kept in your browser's local storage.

Global leaderboard (public): your runner name, best distance, run time, carrots and date per character are posted to MantleDB, a free third-party JSON store, and are visible to everyone. Pick a nickname, not your real name.

Accounts (optional): if you sign in, Google Firebase Authentication keeps your email address or Google account ID, and Cloud Firestore keeps your display name and run history (character, distance, carrots, run time, date) so you can see them on any device. Only you can read your account data.

No ads, no tracking cookies, nothing is sold. Delete local data by clearing this site's data in your browser; signed-in players can erase their cloud data and account from the Profile page.
