Privacy policy
How Mahjong Scoring handles your information.
Accounts and sign-in
If you register with email, we store your display name, email address, and a password hash. If you choose Google sign-in, we use the account identifier, email, and name Google provides to sign you in.
Rooms and scores
We store room names, room codes, player names, and point transfers so room members can see the same scoreboard and signed-in players can review their results. Share your room code with the people you want to invite.
Cookies and browser storage
We use a session cookie to keep you signed in. Your browser stores your language preference and, if you play as a guest, your guest credential. Clearing browser data removes access to that guest identity from the browser. It does not delete shared room records.
