For parents
Bayati is a maths app for grades 7 to 10. Here is what your child can expect and what happens to their data.
No ads and no tracking
Bayati shows no ads and passes no data to advertising companies.
This website sets no analytics cookies, so it needs no consent banner.
No chat, no contact with strangers
Duels have no chat, no free-text names and no profile pictures. Opponents only appear by nickname.
Servers in the EU
Accounts and progress are stored with Supabase in Frankfurt, Germany. We only store what learning needs: the email address for logging in, the solved questions and the progress.
Accounts without a password
Your child logs in with a code sent by email. There is no password.
Without an account they learn the first chapter of their grade as a guest. They can delete the account with all its data at any time in their profile.
Content based on the curriculum
The chapters follow what grades 7 to 10 cover in class. Every topic knows the topics before it, so your child can find gaps on their own.
Cost
Bayati starts free, as a guest and with an account, each with limits. Premium costs €44.99 a year.
