Privacy Policy
Last updated: 17 September 2026
Adaa Study is a social study app developed and operated by Adaa Technology LLC. This page explains plainly what we collect and why, who sees it, and how you delete it.
What we collect
Only what the app needs to work:
- Account data: your email, your nickname, and the photo or avatar look you choose.
- Study data: your subjects, the start and end times of timer sessions, and your weekly goals.
- Friends: whom you added and who added you, and the cheers between you.
- App settings: language, colour mode, timer preferences.
Who sees your data
Only the friends you agreed to add see your name, look, status (studying now or not), daily total and subject names — and you can hide subject names in Settings. There are no public pages, no people search, and your email is never shown to another user.
We do not sell your data or share it with advertisers. There are no ads in the app.
Where it lives
Data is stored with Supabase (servers in the European Union) in a database protected by row-level access rules, so nothing reaches anyone but its owner and their accepted friends. Sign-in emails are sent from our own mail servers.
Your account is shared with the Adaa family (adaa.store): the same email signs in to both, and study data is kept apart from store data.
Deletion
You can archive subjects and remove friends any time inside the app. To delete the account and all its data, send a request from Settings or to our email; we delete it within 7 days.
Children
The app is meant for students aged 13 and over. If we learn of an account for someone younger without a guardian's consent, we delete it.
Changes
When this policy changes we update the date above, and tell you inside the app if the change is material.
