5. Third parties
| Service | Data | Purpose | Legal basis |
|---|---|---|---|
| Google Play / Apple App Store | Purchase transaction (your store account) | Payment, subscription | Contract |
| RevenueCat, Inc. (USA) | Anonymous app user ID, purchase and subscription information, device and platform information | Verifying Premium, restoring purchases | Contract |
| Google AdMob (Google Ireland Ltd.) — free version only | Advertising ID (on iPhone only with tracking permission), device information, approximate location derived from IP address, ad interactions, diagnostic data | Serving ads, frequency capping, measurement and fraud prevention; interest-based personalization only if you consent | Non-personalized ads: legitimate interest. Personalized ads: consent (only in the EEA, the UK and Switzerland, via Google's consent form) |
Your photos, games and statistics are not shared with any of these services.
Ad consent: in the European Economic Area, the United Kingdom and Switzerland your consent to personalized ads is collected with Google's consent form; in these regions you can change your choice in the app under Settings → "Privacy choices". In all other regions (including Türkiye) you are not asked for consent and ads are requested without personalization: AdMob processes the data above to serve ads, cap their frequency, measure them and prevent fraud, but no interest-based targeting is done. On iPhone, App Tracking Transparency permission is requested from everyone; if you decline, your advertising ID is not used and the app works the same. In all cases you can reset your advertising ID or opt out of personalized ads in your device settings.
RevenueCat and Google servers are located outside Türkiye. International transfers are carried out in accordance with Article 9 of the Turkish Personal Data Protection Law (KVKK).
6. Backups and changing phones
If Android's automatic backup to your Google account or iPhone's iCloud backup is on, the operating system may include the app's data in the backup in your own account and restore it when you switch phones. Google or Apple keeps these backups under your account and their terms; we cannot access them. You can turn this off in your device settings.
On a new device, Premium comes back from your store account with "Restore purchases" on the "Scandoku Premium" screen.
7. Notifications
The optional daily reminder is scheduled locally on your phone; no notifications are sent from our servers. You can turn notifications off at any time in your device settings.
8. Children
The app is not directed to children under 13 and does not knowingly collect their data.
9. Retention
On-device data remains until you uninstall the app; device backups remain in your account until you delete them. Data processed by third parties (Google, Apple, RevenueCat) is retained under their own policies.
10. Your rights
Under KVKK (Türkiye) and the GDPR you may request access, rectification, erasure, restriction, objection and portability, and lodge a complaint with a supervisory authority. You control your on-device data directly and can remove all of it by uninstalling the app. Contact: iletisim@turuncukatman.com.tr.
