Playing: no account is needed. Your nickname and answers pass through our relay to the game's host while the game runs. The relay does not store them. The host can download a report of the game.
Your browser: quizzes, your nickname, avatar, theme and language are saved on your own device. A running game is also saved in the host's browser so it can recover after a refresh.
Signing in (optional): Google signs you in, and we keep only Google's account identifier with your saved quizzes. We do not store your email address or name on the server. Quizzes you publish as challenges stay available to anyone with the link.
Other services: Google (sign-in and fonts), Cloudflare (hosting, security and basic analytics), cdnjs (QR code tool) and GitHub Pages (hosting). Images added to a quiz load from wherever their author chose.
Keep nicknames and quiz content free of other people's personal details. To delete your saved quizzes, use Delete in your library. Questions: zyeemzia.com.
