Privacy

A guest needs a nickname. That nickname and your session stay in this browser so you can rejoin a room.

An account adds a username, email, a password stored only as a hash, and an optional avatar and bio. Your public profile shows the name and avatar, not the email.

A room stores the game, who is playing, and what happens in the match. Public rooms can be seen by anyone looking for a game.

The daily challenge can limit one official attempt per network and device each day.
