Privacy policy
Last updated: 10 November 2026
This policy explains which data Tahdir collects, why, and what your rights are, in accordance with Moroccan law 09-08 on the protection of individuals with regard to the processing of personal data.
1. Who is responsible for processing?
The data controller is the publisher of Tahdir, reachable at contact@tahdir.app.
2. What data do we collect?
- Account data: name, email, phone, school, city, levels and subjects taught.
- Teaching content: the classes, lessons and course material you enter or attach, the generated documents and your change requests.
- Technical data: sign-in logs, session identifiers, browser type, needed to run and secure the service.
- Messages: what you send us through the contact form.
3. Why do we use it?
- To create and manage your account and approve teacher-only access requests.
- To generate your documents with your school's identity.
- To improve the service (for instance through your ratings and comments on documents).
- To answer you and inform you about the service.
- To ensure security and prevent abuse.
4. Artificial intelligence
To generate a document, the content of the lesson concerned (titles, objectives, your attached course, your instructions) is sent to our AI provider, Anthropic (Claude models), through its API. Under Anthropic's commercial terms, this data is not used to train its models. PDF files or photos you attach to a lesson are also sent to be transcribed into text.
5. Where is your data stored?
Your data is hosted by Supabase (database and files) in the European Union, encrypted in transit and at rest. Each teacher only accesses their own content; our team can access it only for support, moderation or security.
6. For how long?
Your account data is kept as long as your account is active. You can delete your account at any time from the settings: your lessons, documents and files are then erased. Technical logs are kept for at most 12 months. Rejected access requests are kept for 12 months.
7. Cookies
Tahdir only uses strictly necessary cookies: the sign-in session and the chosen language. No advertising cookies or third-party trackers.
8. Your rights
Under law 09-08, you have the right to access, rectify, object to and delete your data. Write to us at contact@tahdir.app. You can also contact the Moroccan data protection authority (CNDP).
9. Changes
We may update this policy; the date at the top of the page shows the latest version. For significant changes, we'll let you know in the app.
