Saved state & integrity

Everything lives in your browser: card numbers, marks, timestamps, and a checksum. If the checksum ever disagrees with the saved data, we flag it here—handy for keeping play honest without a backend.

How the integrity badge works

Every card stores a timestamp, card ID, your marks, and a checksum in local storage.
The checksum is recalculated on load; if it doesn’t match, we flag it so everyone knows to reset.
No account or server required—perfect for honor-system games where you still want a paper trail.
