Privacy
Last updated 18 September 2026
This page says what the demo keeps about you, why, and for how long. It keeps little, because it needs little.
What is stored
- A session token in your browser's local storage, and the matching record on the server: a random player id, your display name if you chose one, your play-money balance, when the session was created and last used. This is the whole of your “account”.
- Your bets and cash-outs, tied to that player id, as the game's own record of what happened in each round.
- The network address you connected from and the time, per session, to spot one person opening many accounts. This is kept with the session.
- One row per day you connected, by player id, to count how many players come back. No content, just the day.
- Reports the game sends about itself when it hits an error on your device: the error message, the page, and your browser's user-agent string. They are used to fix the game and nothing else.
- Your language and sound choices, in your browser only.
No name, e-mail, phone number, payment detail or account with another service is asked for or stored. There are no advertising trackers and no third-party analytics scripts on this site.
Who processes it
The site runs on Render (hosting and database, EU region) behind Cloudflare (network and DDoS protection). Both see the network traffic in order to carry it. Nobody else receives the data.
How long
A session and everything tied to it is deleted ninety days after its last use. Round records are kept as the game's audit history. Error reports are kept for as long as they are useful for fixing the game and can be deleted on request.
Your choices
Clearing your browser's site data ends your identity here at once; the server copy expires by itself. To have a session's data removed sooner, send its player id through the issue tracker. Where data-protection law gives you rights of access, correction or erasure, the same route exercises them.
Children
The demo is for adults. If you believe a minor has used it, tell us and the session will be removed.
The demo is open source; what it stores can be read in its code, not only on this page.
