Your guest player name is saved in this browser. Local and bot rooms are saved in this browser tab so a match can survive a reload. Local and bot room data is not sent to the online game service.

Accounts and purchases

Online play uses Firebase Authentication and creates an anonymous player ID. If you continue with Google, Google supplies your account identity to Firebase. We store your player ID, display name, profile timestamps, game-style preference, theme access, and Zummon Plus Pass access or payment references. We do not store your Google password or card details.

Online rooms

Online rooms store the room code, player IDs and names, connection state, seat types, board setup, moves, winner, and timing needed for reconnect and cleanup. The public lobby shows only the host name and seat counts. People with the room code or link can see player names and live room state. Disconnected seats are removed after a grace period, and empty rooms are cleaned up.

Rankings

Eligible four-player online matches add each player's display name, wins, and losses to the public leaderboard. Match result IDs are kept to prevent the same result from being counted twice.

Advertising

Google AdSense may show one ad after gameplay for players without Premium Cosmetic access. Google may receive the page URL and IP address and may use cookies or similar technologies to deliver, measure, and personalize ads according to your settings.

Your choices

You can change your player name, sign out, leave an online room, clear this site's browser data, and control ad personalization in Google My Ad Center. Email us to ask about access, correction, or deletion of account data.
