Privacy

We store a random device ID your browser makes the first time it needs one, plus the game data linked to that ID, daily submissions, quiz personal bests, tic-tac-toe outcomes, an optional nickname. Retention runs from 48 hours (leaderboard rows) to 1 year (daily submissions); profile + records stay until you ask us to delete them. We also use Cloudflare Web Analytics, anonymous, cookieless traffic counts only (page views, country, browser), to see how many people visit. No ads and no accounts. We set one functional cookie that stores that same random device ID, so your saved progress can be restored if your browser clears its local storage; it is not used for tracking.
