Plain language. SudokuVs is a small game, not a data product.
Your display name lives with the room so the other player can see it. Room codes and board state exist while the game is open. When the room ends, that match chatter is gone from the live connection.
The browser may remember your name, mute setting, last difficulty, and — if a phone sleeps mid-battle — enough of the match to rejoin this tab. That stays on the device.
Optional Google or X sign-in is only there so we know it’s you. We store an account id, the name the provider gives us, and a private record of finished games (wins, losses, practice, times, moves). Guests do not get a record. To delete a stored account, use the contact path on leespringer.co.
