This Privacy Policy governs the mobile application Combinator (“the App”), operated by STOCKIMG AI YAZILIM TEKNOLOJILERI ANONIM SIRKETI (“the Company”, “we”, “us”), registered in Türkiye.

1. Local-First Operation

Combinator has no accounts. Your saved locks and combinations are stored only on your device, in secure storage (iOS Keychain / Android Keystore). Your practice history and settings are stored locally too. We never receive your combinations. Deleting the App removes this data.

2. Data We Collect

To keep the App stable and improve it, we collect minimal, non-personally identifiable data. It is not used to identify you and it never contains your lock combinations:

• Firebase Analytics: Anonymous usage statistics (e.g. screens reached, practice levels finished, paywall views) tied to a random app instance ID. Google Analytics derives an approximate country or city from your IP address. No advertising identifier is collected.
• Firebase Crashlytics: Technical crash details (e.g. device model, OS version, stack trace) used to fix bugs.
• Firebase Remote Config: Anonymous device attributes (e.g. language, country, app version) used to adjust App settings without an app store update.
• RevenueCat: Validates purchases and restores them across reinstalls, using an anonymous app user ID and your purchase history from Apple or Google. It does not receive your payment card details, and it never receives your combinations.

We do not collect names, email addresses, contacts, precise location or your lock combinations, and we do not sell or share personal information.

3. Third-Party Services

The App interacts with external providers that operate under their own privacy frameworks:

• Google Firebase: For analytics, crash reporting and remote configuration.
• RevenueCat: For subscription tracking and purchase verification.
• App Store / Google Play: For app distribution, payments and platform analytics.

4. Children

The App is suitable for students. We do not collect personal information; the anonymous analytics and crash data described above are the only data processed.

5. International Data Transfers & KVKK / GDPR

Anonymous technical and purchase-state data processed by Firebase and RevenueCat may be stored on servers located outside your country (including outside the EEA and Türkiye). This transfer complies with Article 9 of the Turkish KVKK and relevant GDPR safeguards.

Since your combinations and practice data are stored locally, you can exercise your data rights (access, deletion) simply by clearing the App’s data or uninstalling it.

6. Contact & Changes

We may update this policy occasionally. Continued use of the App constitutes acceptance of the new terms.
