Privacy policy
Last updated: October 2026
This policy describes how PrepaItalia collects, uses and protects your information.
1. Information collected
PrepaItalia uses Firebase anonymous authentication. No data that identifies you directly (no name, no email) is collected. The following is stored: learning progress (per-test estimates, mastery by topic, mock exam history), usage preferences (chosen certification, exam date, settings), an anonymous Firebase-generated identifier, technical data (version, platform, crash reports) and content you flag as incorrect. 2. Use of data
Data is used to sync your progress across devices, improve the experience and the adaptive learning algorithms, fix reported content errors and diagnose technical issues. 3. Legal basis
We process data on the basis of your consent (which you can withdraw at any time) and our legitimate interest in operating, securing and improving the app. We do not process any special categories of personal data. 4. Third-party services
The app uses Google's Firebase services: Firebase Authentication (anonymous auth), Cloud Firestore (progress and reports), Firebase Crashlytics (crash reports) and Firebase Analytics (anonymous, aggregated usage statistics). Premium subscriptions are handled by RevenueCat (which processes the purchase identifier and subscription status), together with the Apple App Store and Google Play. These providers act as data processors. No advertising is shown. 5. International transfers
The providers above (Google/Firebase and RevenueCat) may process data on servers located outside the European Economic Area, including in the United States. Such transfers are covered by the standard contractual clauses approved by the European Commission and the related appropriate safeguards. 6. Retention and deletion
Your progress data is stored locally (via Hive) and synced encrypted 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. 7. Security
Communications with our servers are encrypted via TLS. No method of electronic transmission or storage is 100% secure. 8. Data controller
The data controller is F. Azaza, reachable at contact@azaza.fr. The website is hosted by Firebase Hosting (Google LLC). 9. Children
The app is not directed at children under 14. 10. Your rights
In accordance with the GDPR, you have the right to access, rectify, request deletion or restriction of your data, and to object to processing: contact@azaza.fr. You also have the right to lodge a complaint with the competent supervisory authority, in Italy, the Garante per la protezione dei dati personali (garanteprivacy.it). 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.
