Room information

When you create or join a bingo room, RoundLumo stores the room title and code, player names, cards, called numbers, winners and round state. Impostor rooms store player names, secret words, votes, roles and round state. Room credentials are stored as one-way hashes.

People with a room link or code can see its public game state and player names. Impostor words and roles become public only after the host reveals the round. Do not put sensitive information in a room title or player name.

Information on your device

Your browser keeps room credentials, marked bingo squares and nonogram progress in local storage. This lets you return without an account. Clearing this site's browser data removes those records from your device but does not immediately delete a room from the server. Nonogram progress stays on your device.

The standalone bingo caller and card generator run in your browser. Their draws and generated cards are not sent to the room server or saved in an account.

Retention and use

Room records expire and are deleted seven days after the room is created. Browser local storage remains until you clear it. We use room information to run live games and verify bingo claims; we do not sell it.
