In short: the app keeps your scores and study progress in your account so you can see your progress board and continue on any phone. You can try one practice set as a guest. The app shows ads through Google AdMob. We never sell personal information, and you can delete your account and all study data at any time.

We do not collect your contacts, photos, files, precise location, microphone or camera, or data from other apps. The app does not collect any health information about you. Passwords are handled by Firebase Authentication; HomiLabs never sees or stores them. Only you, signed in as yourself, can read or change your study data, enforced by security rules on the database. Data travels encrypted (HTTPS/TLS) and Google encrypts it at rest. The app has no analytics.

3. Advertising

The app is free and shows banner and interstitial ads through Google AdMob. Ads never appear while you answer questions, sit a mock exam or review answers. We ask Google to limit ads to content rated for teens and older (PG). In the European Economic Area, the UK and Switzerland, and where else required, you are asked for consent first. See how Google uses data from apps that use its services. You can reset or delete your advertising ID in your phone's Settings.

4. Who else handles data

Google acts as our service provider for Firebase Authentication, Cloud Firestore and AdMob. We do not sell personal information and share it with no one else, unless the law requires it. Google may process data in other countries under its own safeguards.

5. How long we keep it

Your account and study data are kept while your account exists. When you delete your account, your study data and sign-in account are deleted permanently, within 30 days including backups.

6. Your choices and rights

7. Children

The app is intended for medical students and graduates. It is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has created an account, contact us and we will delete it.
