Local game progress
An unfinished Classic or Daily run is stored in your browser’s local storage so a refresh can restore it. This data stays on the device and is removed when the run finishes or browser storage is cleared.
Published results
If you choose Publish, the service stores your public nickname, mode, period, verified score, losses, completion duration, cabinet choices, action-log hash, share slug, and timestamps. This data supports ranking and a permanent result page. Do not use a real name if you prefer not to make it public.
Anonymous identifiers and abuse prevention
A random HttpOnly device cookie is converted to an HMAC hash before storage. The raw cookie is not written to the leaderboard. The server also uses a secret, short-term hash of network information as part of a coarse submission window; raw IP addresses are not stored in the game tables. Submission windows may be deleted after they are no longer useful.
Analytics and control
Vercel Web Analytics and Speed Insights may provide privacy-oriented traffic and performance measurements after deployment. No advertising or cross-site marketing tracker is included. You can remove local progress by clearing site storage and request removal of a public result through the contact page.
