Cookie Policy
The game uses limited browser storage to remember your settings and protect score submissions.
Essential session cookie
A short-lived first-party PHP session cookie supports CSRF protection when a score is submitted. It does not contain your nickname or game record, and it is marked HttpOnly and SameSite=Lax.
Local storage
Local storage keeps your anonymous player key, personal best times, theme preference, and selected controls on this device. You can clear it through your browser settings; doing so may reset the local player card.
Optional services
The Share result button uses the browser’s built-in share sheet or clipboard only after you press it. It does not set a new cookie or create a share-history record on this site. The app you choose may handle the shared text and link under its own policy.
