Student privacy, in plain words

Students join Chalkplay with a code or a link and a first name or nickname: no account, no email, no password. Live games save nothing, homework keeps only a name and a score for the teacher, and no student ever sees an ad.

What happens to student data

  1. Students join with a first nameFor a live game they type the code from the board; for homework they open the teacher's link. Then they type a first name or nickname, up to 20 characters. No account is created.
  2. Only a name and a score travelWhen they finish, the name they typed and their score (how many they got right and wrong) go to the teacher. Their answers stay on their own device.
  3. Live games save nothingIn a live game, names and scores pass between the students' devices and the teacher's screen while the game is open, and are gone when the teacher closes it.
  4. Homework keeps a name and a scoreFor homework, the name, score, number of tries and finish time are saved for the teacher who set it, until a year after the due date. The teacher can remove a result or the whole homework at any time.

What's free and what's paid

Every plan collects the same minimum from students and shows them no ads.

Homework results are deleted a year after the due date on the free plan. They stay longer while the teacher has Pro, a trial or a school seat, and are deleted once that ends.

We don't have a standard data processing agreement for schools yet. If your school or district needs one, or a vendor privacy form filled in, write to support@chalkplay.app.

What we collect

Students: the first name or nickname they type, and their score. For homework, also how many tries they took and when they finished, and their browser keeps the name and a random code for that homework, so another try counts as the same student. Nothing else: no email, no password, no photo, no age and no school.

Teachers: the name, email address and profile picture that Google shares when they sign in, and the activities and homework they make.

Everyone: short-lived server logs to keep the site running, and visit counts on public pages and library activities, made with Cloudflare Web Analytics and our own Plausible server without cookies. Neither runs on the pages students use to join a live game or do homework.

Embedded activities: when a teacher's activity is embedded on another website, we count its plays by that site's address for the teacher, and nothing about who played.

Where it's stored

Homework results and teachers' accounts are kept in our Supabase database in Frankfurt, Germany, and our server functions run in Frankfurt on Vercel. Live games pass through Supabase's real-time service without being saved. Our privacy policy lists every company that handles data for us, and where.

What we never do

We never show ads to students (or anyone else), never build advertising profiles, never sell or rent personal data, and never use anything students type to train AI models. There are no advertising or cross-site tracking cookies.

Laws and certifications

We handle personal data under the EU's General Data Protection Regulation (GDPR), as our privacy policy sets out. Chalkplay has no privacy seal or certification. Accounts are for teachers and other adults; students never create one. If your school needs to check Chalkplay against COPPA, FERPA or a state student privacy law, write to support@chalkplay.app and we'll answer your questions.

All 33 templates work without student accounts

Whichever template you use, students join the same way: a code or a link, and a first name.
