1. Who is responsible
Mubtada operates Mubtadaʾ and is the controller of your data. Contact: hello@mubtada.app.
2. What we collect
Account
- Email address and a password (stored hashed — we never see it).
- The first name and age band you give the tutor, so lessons are pitched to you.
Learning
- Your answers in the placement interview and its summary.
- Your progress: which concepts you've studied, scores, mistakes the tutor is watching, and your review schedule; the words you've learned and how well you know each; the days you studied (Hādī's lamp); and the badges you've earned.
- Written answers you submit for grading, and messages you send the tutor in chat.
- Where you are inside a lesson, so you can resume.
Subscription
- Your subscription status, plan and renewal or trial end date, as reported by the store via RevenueCat. We never see your card details.
Device
- A push notification token, only if you turn reminders on.
- Your device's time zone offset and chosen reminder hour, only if you turn reminders on.
Waitlist
- If you join the launch waitlist on this website: the email address you give us, which form you used, whether you were on an iPhone, an Android phone or something else, and what brought you here — the campaign tags on the link you followed (which of our ads or posts it was) and the website that sent you. We use them to send you two emails, one confirming your place on the list and one on launch day, and to learn which of our ads work. No cookies or tracking pixels are involved. Every email has a link to leave the list, or email hello@mubtada.app.
We do not collect location, contacts, photos, or advertising identifiers.
3. Why we use it
- To run your account and sign you in.
- To write lessons for you, grade your answers and answer your questions — this is the product.
- To bill you correctly for a subscription bought through Apple or Google.
- To send the notifications you asked for: a lesson being ready, a daily nudge, a trial-ending reminder.
- To fix problems and improve the tutor. We may review anonymised lesson output for quality.
4. AI processing
Lessons, grading and chat replies are generated by Claude, a large language model provided by Anthropic. If Anthropic is unavailable, the same request goes to a backup provider, Moonshot AI, so your lesson still arrives. To do that, we send the model the text needed for the task: your first name, the concept being taught, your progress summary, your written answer or message, and recent chat turns. We do not send your email address or subscription details. Anthropic's API terms say it does not train its models on API data; Moonshot AI, to our knowledge, does not either. We will update this section if that changes.
5. Who else handles your data
- Convex — hosts our database and runs our backend.
- RevenueCat — manages subscriptions and receipts from the App Store and Google Play.
- Apple / Google — process payments under their own privacy policies.
- Expo — delivers push notifications to your device.
- Resend — sends our emails: password reset codes, and the waitlist's two emails.
- Anthropic — generates lessons and feedback, as described above.
- Moonshot AI — the backup when Anthropic is unavailable.
These providers act on our instructions. We do not sell or rent your data to anyone.
6. How long we keep it
For as long as you have an account. When you delete your account from Profile, your profile, progress, cards, chat and push tokens are deleted from our database immediately. Store purchase records are kept by Apple or Google under their rules. Backups roll off within 30 days.
Waitlist addresses are kept until launch day's email has gone out. If you leave the list, your address stays only marked as having left, so it is never emailed again — email hello@mubtada.app to have it erased entirely.
7. Deleting your account
You can delete your account yourself, from inside the app, at any time. It takes four taps and there is no waiting period, no email to confirm, and nobody to ask.
- Open Mubtadaʾ and sign in, if you are not already.
- On Today, tap the circle with your initial in the top right to open Profile.
- Scroll to Account, at the foot of the page.
- Tap Delete my account and everything in it, then Delete everything to confirm.
Everything of yours is removed from our database immediately: your profile and settings, your placement and the tutor's notes on you, every lesson written for you, your path and mastery scores, your review cards, your words, your lamp days and badges, your session history, your chat with Hādī, any push notification token, and the sign-in credentials themselves. Nothing is archived and nothing is recoverable — if you come back later, you start from the placement interview again. Backups containing your data roll off within 30 days.
A subscription is separate. Deleting your account does not cancel it, because Apple and Google hold the billing relationship, not us. Cancel in your App Store or Google Play subscription settings — ideally before you delete, since Profile is also where the shortcut to it lives. Your purchase record stays with the store under its own rules.
If you cannot get into the app — you have lost the device, or you cannot sign in — email hello@mubtada.app from the address on the account and ask us to delete it. We will confirm when it is done, within two working days.
8. Your rights
- See what we hold about you — email us and we will send it.
- Correct your name or age band in Profile at any time.
- Delete everything — see the steps above.
- Turn reminders off — Profile → Reminders, or in your device settings.
- Complain to your local data protection authority if you think we've got it wrong.
9. Children
Mubtadaʾ is for adults. We do not knowingly collect data from anyone under 18, and the app asks for an age band before an account can be created. If you believe a child has created an account, tell us and we will delete it.
10. Security
Data is encrypted in transit. Passwords are hashed. Access to the database is limited to what the app needs and to the people who run it.
11. Changes
We will tell you in the app or by email before a change that affects you takes effect. The date at the top is the version you are reading.
