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
- Use your own email, and keep your sign-in codes to yourself.
- Students under 13 need a parent's or guardian's permission.
- You can delete your account at any time from Settings.
Using Bayyina well
- Use it to learn. Don't use it to cheat in exams or graded work where that isn't allowed.
- Don't try to break, overload or misuse the service or its AI, or get around the limits.
- Don't write anything illegal, hateful or harmful in it.
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.
