3. Data Processing Overview
SoulTune operates under a privacy-by-design principle. We do not collect, transmit, or store personal data on external servers.
3.1 Data Stored Locally on Your Device
Legal Basis: Art. 6(1)(b) GDPR (Performance of a contract / service provision)
| Data Type | Purpose | Storage Location |

| Processing history (temporary) | Undo/redo functionality | App sandbox (local device) |
Data Deletion: All data is automatically deleted when you uninstall the app or manually clear app data via device settings.

SoulTune requires the following permissions:
- 📁 Storage/Media Access: To read and process your music files. On Android 11+, we use Scoped Storage (access only to files you explicitly select).
- 🌐 Internet Access: Required for the optional in-app browser feature only. No background data transmission occurs.
Legal Basis: Art. 6(1)(b) GDPR (Necessary for app functionality)
3.3 In-App Browser (Web View)
SoulTune includes an optional web browser for opening external links.
- Data Processed: URLs visited, timestamps, cookies (stored locally)
- Third-Party Websites: When you visit external websites via the browser, those sites may collect data according to their own privacy policies
- No Tracking: We do not track or log your browsing activity
Legal Basis: Art. 6(1)(f) GDPR (Legitimate interest in providing full app functionality)

Important: We do not have access to this data. For inquiries, contact the respective store operator directly.
6. International Data Transfers
For EU/EEA Users: Since all data is stored locally on your device, no international data transfers occur. We do not operate servers or transfer data outside the EU/EEA.
Exception: If you use the in-app browser to visit websites hosted outside the EU/EEA, standard GDPR safeguards (e.g., Standard Contractual Clauses) apply to those third-party services.
7. Data Security
