Cookies and browser storage

The daily service uses one necessary cookie, zq_player, to recognize the browser that starts a ranked run or sets a display name. The cookie expires after 90 days and can be cleared in Settings.

The game stores your sound and motion preferences, tutorial progress and Quick Play best locally. Optional analytics identifiers are created only after opt-in. Use Settings to change the choice or reset your data.

Adventure also uses the guest cookie and local storage to restore the current puzzle. The Sparks wallet shows the guest balance from the server.
