Quick Play saves your personal best and preferences in this browser. Joining the Daily Challenge or saving a display name creates an anonymous ID in a first-party cookie. The cookie lets this browser submit scores and manage its data.

The daily service keeps round dates, scores, chain lengths and an optional public display name. It uses short-lived rate counters to protect the daily service. Where the reverse proxy provides a trusted IP address, the rate key is hashed using a server secret. Individual tap lists are checked and discarded.

In Settings, select Reset my data to remove this browser’s preferences and submitted daily scores. The service also expires inactive identities after 90 days and removes round records after one day when scheduled cleanup runs.

Optional play analytics use first-party storage only after you enable them in Settings. You can turn them off at any time.

Adventure saves the current puzzle in this browser. The guest profile keeps verified progress, QUBE actions and the Sparks ledger on the server. Reset my data in Quick Play Settings removes that guest profile and its history.
