Your privacy is important to us
Concert record data contains no personal information and is stored locally on your device only. However, for premium features (background customization), we collect subscription purchase history and user identifiers via RevenueCat, and minimal authentication information when using Apple Sign In.
Collected subscription purchase history is used solely for providing premium features. Authentication information is used only for maintaining app personal settings. Concert record data functions offline, but we perform minimal server communication for payment and authentication processing.
Concert record data is not shared with third parties. However, for subscription management we share purchase history with RevenueCat Inc. (US), and for authentication we share authentication information with Apple Inc. (various countries). Both companies comply with appropriate privacy protection standards. RevenueCat Privacy Policy: https://www.revenuecat.com/privacy
All data is stored locally using Apple's SwiftData framework (iOS 17+) with iOS's standard security measures. Authentication tokens are securely stored in iOS Keychain. Enable device encryption and use Face ID/Touch ID for enhanced security.
You have full control over your data. You can view, edit, export, or delete your data at any time within the app. Deletion is permanent and irreversible.
Our app does not knowingly collect information from children under 13. The app is designed for general audiences interested in classical music.
Concert record data remains on your device without international transfer. However, subscription information to RevenueCat (US-based) and authentication information to Apple (various countries) may be transferred internationally under appropriate protection standards.
We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date.
