Privacy Policy

Last updated: 5 July 2026

Plain-English summary. Solo games, puzzles, lessons and Pass & Play stay on your device. Optional online play uses an anonymous identity and sends only the information required to match players, run the game and maintain Ranked ratings. Checkers has no ads, analytics or cross-app tracking.

Offline play

Playing against the on-device AI and Pass & Play work fully offline. Your settings, profile name, chosen avatar, country, game history, rating and statistics are stored only on your device. This information is removed when you delete the app. We do not use analytics, advertising or third-party tracking SDKs, the Advertising Identifier, or App Tracking Transparency.

Optional online multiplayer

Nothing in this section happens unless you choose Quick Match, a Private room or a Ranked match.

When you first play online, Supabase Anonymous Auth creates a random device identity. It requires no email or password. Ranked play optionally uses Sign in with Apple. Your opponent sees your chosen display name, or a generated name such as “Player####”. There is no free-text chat.

Online play processes:

your anonymous user ID;
your display name or Ranked username;
your skill rating and win, draw and loss record;
your IP address while establishing and routing the connection;
the move log for the current match.

Match move logs are retained only long enough to support reconnection and are pruned after the match, except for the result of a Ranked game, which is retained to maintain your rating.
