What we keep
- A random device ID, stored in your browser, so your game and your daily High Score limit follow this device. It is not linked to your name.
- Your games (cards dealt, moves and bankroll) on our game server, for 14 days, so you can reload the page mid-shoe.
- Scores you save: your three initials, your flag and the score, shown on the leaderboards.
- A one-way hash of your IP address, used only to limit High Score games per network and stop bots. We never store the address itself.
Who helps
Cloudflare serves the site, checks that High Score games are played by a person (Turnstile), and tells us your country so we can suggest a flag. Our game server runs on Railway. Fonts load from Google Fonts.
