Cookie policy

Cookies this site sets today

None. Sudoku24x7 currently sets zero cookies. Your settings, saved games, and stats are stored in your browser's localStorage instead, which is a different browser storage mechanism — it stays on your device, isn't sent with page requests the way a cookie is, and isn't shared across sites. See the privacy policy for exactly what's stored there.

What a future analytics integration would add

We plan to add Google Analytics, which is not active in the current build. Once it is, Google Analytics typically sets a small number of first-party cookies to distinguish unique visitors and sessions. This section will be updated with the specific cookie names and durations before that integration goes live.

What a future ads integration would add

This site has reserved, empty ad slots, but no ad code runs today — nothing is loaded into them. If that changes, an ad network (Google or otherwise) would set its own cookies to serve ads, including personalized ones based on browsing history across sites, unless you decline. Visitors in the EEA, UK, and Switzerland would see a consent prompt before any such cookie is set, and this policy would be updated with the specific details at that point — not retroactively, not quietly.

Managing cookies in your browser

Since this site sets none today, there's nothing to clear specifically for Sudoku24x7. Your browser's own settings let you block or clear cookies and site storage generally, for any site, at any time.
