Sudoku Genius Edition Privacy
Last updated: 28 August 2026
Optional website analytics
With your permission, Google Analytics helps us understand page visits and use of Sudoku features. It receives a browser identifier, approximate location, device information and selected gameplay events. We do not send your puzzle entries, player name, private content or payment details.
Analytics is off by default. Your advertising choice is separate. Declining or withdrawing analytics does not change free gameplay or saved progress. You can return here through Settings → Privacy choices → Analytics.
Analytics: Off
Withdrawing stops future Analytics collection and removes this site’s Analytics cookies. It does not erase information already received by Google. For its processing practices, see: Google’s privacy policy
Core Sudoku gameplay, puzzles and saved progress work offline. No account, email address, phone number or social login is required.
International leaderboard
The optional world leaderboard sends the public player name you choose, a random anonymous player identifier, your score statistics, and the app-store platform to our leaderboard service. Other players can see your chosen name, platform, score and rank.
The anonymous identifier and a private device token keep your profile associated with your installation. The private token is never displayed publicly. Network providers necessarily process IP addresses to deliver the service; the leaderboard keeps only a short-lived one-way hash for abuse-rate limiting and does not store the raw address.
You can change your public name or remove your public leaderboard profile from the World tab at any time. If you do not join, no leaderboard profile is created. Scores wait locally while offline and sync when connectivity returns.
Competitive matches, battles and presence
Optional online battles send your chosen public player name, anonymous player identifier, team name when used, invite code, online-presence heartbeat, puzzle result, completion time and mistake count. Other battle participants can see the chosen name, team, online or away status, score, result and rank.
Presence is considered online only while a recent heartbeat exists. Battle rooms expire after 24 hours and expired battle data is removed during routine service cleanup. The app may keep the active invite code and last-seen counts on your device to provide optional battle notifications. Android may delay background alerts to save battery.
Offline pass-and-play battles never send battle names or results to the internet. You can leave an online battle or disable battle alerts from the Battle tab.
Optional ranked play also processes a rating, rating uncertainty, wins, losses, draws, streaks, match identifiers, reconnect state, server-validated final board, elapsed time, mistakes, move-integrity signals and limited anti-abuse risk signals. Public profiles show only the chosen name, approximate competitive statistics and an optional user-selected country. Precise GPS is not collected for rankings.
Advertising and purchases
Where enabled, Google AdMob and the applicable app store may process device, advertising, consent, transaction and diagnostic information under their own terms. Purchases are handled by the store; we do not receive your full payment-card details.
