In short. The current version of Novaku Flag Quiz has no accounts and never asks for your name, email, photos, contacts or location. Your progress stays on your device. The app shows ads through Google AdMob, sells optional Pro purchases through Google Play and RevenueCat, and sends crash reports to Sentry so we can fix bugs. Those services receive the limited technical data described below. We never sell your data.
1. Who is responsible
Novaku Flag Quiz is published by Novaku, an independent developer established in Spain, which is the data controller under Regulation (EU) 2016/679 (GDPR) and Spanish Organic Law 3/2018 (LOPDGDD).
Contact for privacy matters: novakuapp@gmail.com (subject "Privacy – Flag Quiz").
2. What stays on your device
Lessons and stars, XP, hearts, streaks, daily challenges (generated on your device), review and mastery progress, and settings (language and notification preferences) are stored only on your device. They are not sent to us and are deleted when you uninstall the app or clear its data.
3. Notifications
If you allow notifications, the app shows reminders (for example, to keep your streak or when your hearts are full again). They are scheduled on your device; we do not send them from a server and no notification data is sent to us. You can turn them off in Profile → Settings → Notifications or in your Android settings.

5. Your choices about ads
- In the EEA, the UK and Switzerland, a consent form is shown on first launch. You can change your choice at any time in Profile → Settings → Ads → Privacy options.
- You can reset or delete your advertising ID in your device's Android settings (Google → Ads).
- Pro removes banner, interstitial and app-open ads. Reward videos are always optional.
6. Sharing
We do not sell or rent personal data. Data is only processed by the providers listed in section 4.
7. International transfers
Google and RevenueCat may process data in the United States, and Sentry's support staff may access EU-stored reports from the United States. These transfers rely on the EU–US Data Privacy Framework and/or the European Commission's Standard Contractual Clauses.
8. Retention
- On-device data: until you uninstall the app or clear its data.
- AdMob and Firebase data: according to Google's retention periods.
- Purchase records at RevenueCat: while needed to keep your purchase or subscription active and restorable, and to comply with accounting and tax obligations.
- Crash reports at Sentry: deleted automatically after at most 90 days.
9. Deleting your data
The current version has no account to delete. To remove everything stored by the app, uninstall it or go to Android Settings → Apps → Novaku Flag Quiz → Storage → Clear data. To delete purchase or crash records, or data from an earlier test version, write to us (see section 10). Uninstalling does not cancel a subscription: cancel it in Google Play → Payments & subscriptions → Subscriptions. More details on the data deletion page.
10. Your rights
Under GDPR Arts. 15–22 you can request access, rectification, erasure, restriction, portability, object to processing based on legitimate interest, and withdraw consent at any time without affecting earlier processing. Write to novakuapp@gmail.com; we answer within one month. Because we hold no account data, we may ask for the purchase order number (GPA.…) from your Google Play receipt to locate purchase records.
You can also complain to the Spanish Data Protection Agency (AEPD, C/ Jorge Juan 6, 28001 Madrid) or the authority of your EU/EEA country.
11. Children
Novaku Flag Quiz is a general-audience geography game and is not directed at children under 13. We do not knowingly collect personal data from children. If you believe a child has provided data, contact us and we will help delete it.
12. Security
All data sent by the app travels encrypted (HTTPS/TLS). The only permission the app asks you for is to show notifications, which is optional. It does not use location, camera, microphone, contacts or files.
13. Changes
We may update this policy; the date at the top shows the latest version. If we add features that process more data (for example, optional sign-in or cloud sync), we will update this policy before releasing them. Significant changes will be announced in the app or its store listing.
