Privacy.

Kick-off records aggregate page views, traffic source categories and game starts and completions so we can understand how the games are used. No tracking cookies or persistent analytics IDs are placed on your device. Answers, names and room codes are not sent to analytics.

A daily salted hash of network address and browser family estimates daily visitors. Analytics stores the hash, not the raw address or full browser string, and retains events for 90 days. A new hash is used each day. Sources are recognised source tags or website categories, not full referring URLs. Your browser’s Do Not Track or Global Privacy Control preference disables this tracking.

Game progress uses local browser storage. Multiplayer uses a session token and temporarily stores player names and game state to run your room, which expires after two hours. Room codes are for sharing with your players. The analytics dashboard is accessible only to the website owner.

Leaderboard play uses a public nickname and either your signed-in account ID or a random guest browser ID. The guest cookie lasts up to 90 days and is used to remember your daily Guess Who? attempt and count each browser once in Kick-off score comparisons. Kick-off compares your result with the best score of each other account or guest browser on the same set. Game answers, deadlines and results are stored on the server for verification; game sessions expire after 24 hours and old session records are cleaned after 90 days. Daily ranked-attempt records, scores, player profiles and first perfect achievements are retained while the service operates. Nicknames, scores and achievement dates appear publicly on the world leaderboard and Hall of Fame. Your email is not displayed there. Guest Guess Who? scores are labelled Guest on the leaderboard.
