Terms of use

Last updated 14 November 2026

Bayyina is a study tool: you write by hand, and an AI tutor marks and explains your work. By using it you agree to these terms and to our privacy policy.

The service

Bayyina is made by Hsafa (حصافة), hsafa.com, in Saudi Arabia. For now it's free, by invitation, with a limit on AI uses each day and month. If we add paid plans, we'll tell you first, and nothing will be charged without your clear choice.

Your account

Using Bayyina well

We may pause or close an account that breaks these terms.

The AI tutor

The tutor is an AI. It checks its marks where it can, but it can still be wrong. Use it to learn and check important answers; don't rely on it for decisions about health, money, religion or the law. Questions of فقه should go to a qualified scholar.

Your work

What you write is yours. You allow us to store it and send it to the AI services described in the privacy policy, only to run Bayyina for you.

Our part

We work to keep Bayyina running and your work safe, but we can't promise it will always be available or free of errors. As far as the law allows, Bayyina is provided as it is, and we aren't liable for indirect losses from using it.

Changes and law

We may update these terms; we'll update the date above and tell you in the app if the change matters. These terms follow the laws of Saudi Arabia. Questions: support@hsafa.com.
