Classroom Clicker lets a teacher, counselor or organizer run quizzes where participants answer with printed cards. This page explains what information the site keeps, why, who can see it, and how to delete it. In short: we keep only what is needed to run your games, it stays private to your account, and you can delete it at any time.
Two kinds of people
- Account holders sign up with their own email address and run games. Account holders must be adults.
- Participants are the people who answer with cards, often children. They never sign up, sign in, or use a device on this site. An account holder enters their names.
What we keep about account holders
- Your name and email address.
- Your password, stored only as a one-way scrambled hash that can't be turned back into the password.
- When the account was created, when the email was confirmed, and when you last signed in.
- A record of emails the site sent you (type, time and whether it was accepted for delivery). The links inside those emails are never stored.
- For security, the address of the connection used for sign-in, sign-up, password-reset and report requests, kept briefly to stop repeated attempts.
What we keep about participants
- The name the account holder typed, and optionally a grade and a class or group.
- The number of the printed card assigned to them.
- In each game: the answer read from their card for each question, and their points and place.
By adding participants, the account holder confirms they have permission to do so (for example from the school, camp, or parents). Use first names or nicknames if full names aren't needed. Participant information is never shown publicly and never used for anything except running that account's games.
Who can see it
- Your participants, quizzes, games and results are private to your account. Other account holders can't see them.
- The presentation and scanner links of a game show that game's questions and participant names to anyone you give those links to, so share them only with people helping you run the game.
- Quizzes you choose to publish in the public library are visible to everyone: the questions, answers and listing details, plus your name only if you choose to show it. Participants, scores and game results are never published.
- The person who runs this site can see accounts and their content when needed to operate the service, investigate reports or abuse, or answer a request from you.
What we don't do
- No advertising, no selling or renting of data, and no tracking or analytics cookies.
- The only cookie is the one that keeps you signed in.
- Scanning happens in the scanner's browser. Camera images are not uploaded or stored; only the card numbers and answers it reads are sent.
Services we rely on
The site is hosted by Vercel, the database and live updates run on Supabase, and email is sent through Google's Gmail. These providers process data only to provide their service to us.
Deleting information
- Participants: delete them under Participants. Their card stops working and is never reused. Past game results keep their name unless you choose Erase permanently, which replaces it with “Deleted participant”.
- Quizzes and games: delete them from their pages. Copies that other people made of a quiz you published belong to them.
- Your whole account: Settings, then Delete account. This removes your account and everything in it from the live database immediately, and you get an email confirming it.
Security
All traffic is encrypted (HTTPS). Passwords are hashed, sign-in attempts are rate-limited, every account's data is separated on the server, and changing your password signs out your other devices.
