What stays on this device

Shared play history

The latest 100 completed games in this browser include player name, completion time, elapsed time, moves, board size, and a game ID. Everyone using this browser can see them. Older device results are never uploaded when someone signs in. A newly completed ranked game is saved both online and in this device history. Clear it with “Clear device history” in Play history; deleting a cloud account does not erase other players’ device records.

Sign-in session and preferences

If you sign in, the browser stores your Supabase authentication session so you can stay signed in. Sign out before handing a shared device to someone else. Music and sound-effect choices are also stored in this browser.

Offline files

The browser caches the game pages, code, illustrations, icons, and music for offline play. Clearing site data removes these files and local history. Private browsing or browser cleanup may remove them sooner.

Optional online account and rankings

Google handles the Google sign-in step, and Supabase stores the linked account, your chosen public nickname, server-side ranked round state, and every completed verified result. A result includes its game mode, board size, time, moves, and completion date. The creator can administer this online game data. A ranked round is checked and timed by the server; it cannot pause.

Public leaderboards show only your nickname and best verified time and moves in each category. Your Google name and email are not displayed there. Other players cannot open your full cloud history. Rankings are available to guests when online.

See Google’s Privacy Policy and Supabase’s Privacy Policy for those services’ practices.

Tracking and permissions

The game has no ads or analytics. Its artwork, font, code, and music files are served with the game. Optional sound effects are generated on your device. The game does not request your camera, microphone, contacts, or location.

Feedback and external links

If you choose to contact Shammuspee through WhatsApp or Instagram, that service handles the information you share under its own privacy terms. Your message and the profile details that service makes visible are shared with the creator so they can respond.

Opening a feedback link does not automatically send a message or attach your game results. Avoid including sensitive information in feedback.

Your choices

Play as a guest or sign out at any time. In Account, “Delete cloud account and results” removes your online profile and verified history. It does not clear the shared history on this device. Use the separate “Clear device history” control to remove that record for everyone using this browser. To remove the saved session, audio preferences, and offline files too, clear this game’s browser site data.

Removing the home-screen icon may not clear browser storage. If you clear offline files, reopen the game online before expecting offline play.
