Privacy policy
Last updated: October 2026
This policy describes how PrepaEspaña collects, uses and protects your information.
1. Data controller
The data controller is F. Azaza, publisher of the PrepaEspaña app. For any question about your data or to exercise your rights: contact@azaza.fr 2. Information collected
PrepaEspaña uses anonymous Firebase authentication. No data that identifies you directly (no name, no email) is collected. The following data is stored: learning progress (estimated scores per test, mastery by topic, mock exam history), usage preferences (target level, exam date, settings), an anonymous identifier generated by Firebase, technical data (version, platform, crash reports) and the content you report as incorrect. 3. Legal basis
We process your data on the following GDPR bases: your consent (which you can withdraw at any time), performance of the service you request (progress sync, subscription management) and our legitimate interest in ensuring the operation, security and improvement of the app. 4. Use of data
Data is used to sync your progress across devices, improve the experience and adaptive learning algorithms, fix reported content errors and diagnose technical issues. 5. Third-party services
The app uses Google Firebase services: Firebase Authentication (anonymous auth), Cloud Firestore (progress and reports), Firebase Crashlytics (crash reports) and Firebase Analytics (aggregated usage statistics). Payments (premium subscriptions) are handled by RevenueCat together with the App Store and Google Play. These providers act as processors on our behalf. No advertising is shown. 6. International transfers
Some of these providers (Google/Firebase, RevenueCat) may process data on servers located outside the European Union, in particular in the United States. These transfers are covered by the safeguards provided for by the GDPR, in particular the European Commission's standard contractual clauses. 7. Storage and retention
Your progress data is stored locally (via Hive) and synced in encrypted form with Cloud Firestore. Your data is kept as long as you use the app. You can ask for its deletion at any time by writing to contact@azaza.fr with the name of the app. We delete your data within 30 days and confirm it by email. Uninstalling the app does not delete the data kept online. Technical and diagnostic statistics are kept for at most 14 months. 8. Security
Communications with our servers are encrypted via TLS. No method of electronic transmission or storage is 100% secure. 9. Protection of minors
The app is not intended for children under 13. 10. Your rights
Under the GDPR, you have the right to access, rectify, request deletion or restriction of, object to the processing of, and port your data: contact@azaza.fr. You also have the right to lodge a complaint with the competent supervisory authority, in particular the Spanish Data Protection Agency (AEPD), www.aepd.es. 11. Changes
Changes will be posted on this page with an updated date. 12. Assisted correction (optional)
The app can review the texts you write in the writing-practice section. This feature is optional and only runs after you explicitly agree to it. When you ask for a review, the text you have just written is sent to Google (Gemini) for analysis; under that service's terms, Google may use it to improve its services, including through human review. We therefore recommend not including sensitive personal information. No text is ever sent without your request.
