Privacy and local data

The game needs no account and uses no ad tracking, analytics SDKs or third-party APIs. It does not read browsing history or other webpage contents.

What is saved?

Current deal, moves, undo/hint counts, visible play time, preferences and completed records. Progress and settings use localStorage; the extension record book also uses Chrome storage.local.

Sharing records with the extension

When installed, the extension and this official game site merge completed records in the same Chrome profile. Progress and settings are not shared. Records are not uploaded to a game server and do not sync across devices.

Removing data

Clear this site’s browser data to remove web saves. Uninstalling the extension removes its local data. Firebase Hosting serves the site and may process standard connection/server logs; those do not contain game saves.
