Privacy Policy
Last updated: October 18, 2026
This policy applies to Sheet Check, the Excel-style spreadsheet minesweeper game on this site.
Data kept on your device
The game remembers your best times, the file name you set, your language, the report size you last chose, and, if you play in a room, your nickname and the rooms you joined recently. This information is stored only in the browser you play on.
To delete it, clear this site's data in your browser settings.
Playing in a room
- When you start or join a room, your nickname and your moves (the cells you open and flag) are sent to the game server so the other players in the room can see them.
- Everyone in the same room can see your nickname and moves.
- The game server runs on Cloudflare, and room data is used only to run the game.
- Room data is deleted automatically about one hour after the room is no longer in use. When you leave a room, your nickname is removed from it.
