Privacy Policy
Updated: June 14, 2026
We collect the minimum data — only what's needed to run the app and improve it. We never sell your data to third parties.
1. Who processes the data
The data controller for the AJDE app is Gleb Matsko. For privacy questions, email support@ajde.io.
2. What data we process
- Account. If you sign in with Apple, Google, or email, we store an identifier and your email address to sync progress across devices.
- Learning progress. Completed lessons, words, streaks, and settings — so you don't lose progress.
- Subscription status. Whether AJDE+ is active and its type — to grant access to paid features.
- Usage analytics. Anonymized events (which screens are opened, which lessons are taken) — to understand what to improve.
- Crash reports. Technical data about app errors, so we can fix them.
We do not collect or store payment card details — payment is handled entirely on Apple's side.
3. Why we do this
- to make the app work and store your progress;
- to grant access to paid features;
- to find bugs and improve the learning experience.
4. Who data is shared with
We use trusted processors that handle data strictly on our behalf:
- Apple (App Store, StoreKit) — payments and subscriptions.
- RevenueCat — subscription status tracking.
- Supabase — account and progress sync.
- PostHog — analytics and product improvement.
- Sentry — crash reports.
We do not sell your data or share it for third-party advertising.
5. Storage and deletion
We keep data while your account exists and as long as it's needed to run the app. You can delete your account and all associated data right in the app — «Account» → «Delete account». Deleted data cannot be recovered.
6. Your rights
You can request access to your data, its correction or deletion, and withdraw consent to processing. If you are in the EU, you have rights under the GDPR. To exercise them, email support@ajde.io.
7. Children
The app is not intended for children under 13, and we do not knowingly collect their data. If you believe this has happened, let us know and we will delete such data.
8. Changes to this policy
We may update this policy. The current version is always here, with the update date at the top of the page.
