3. Data Storage and Security

3.1 Local File Processing and Storage

The 432 Hz Converter app operates entirely offline for audio processing. Your imported audio files are securely copied to the app's private internal directory and converted locally using advanced technology with proprietary algorithms. All audio files remain on your device and are never transmitted to external servers.

3.2 File Management

The app maintains an internal media library of your imported files and provides you with full control to manually delete files to free up storage space. Converted files are saved to your device's public directories (iOS Documents folder or Android Music folder) for easy access and sharing.

3.3 Secure Account Data

Your anonymous device identifier and purchase data are stored using secure storage encryption. We implement appropriate technical and organizational measures to protect your account information against unauthorized access, alteration, or disclosure.

3.4 Data Retention

Audio files remain on your device under your complete control. Account and usage data are retained only for the minimum period necessary to provide service, manage subscriptions, and fulfill legal obligations.

The app integrates with the following third-party services:

• Apple App Store and Google Play Store for in-app purchases and subscription management

These third parties have their own privacy policies governing their use of your information. We recommend reviewing the privacy policies of Apple App Store and Google Play Store regarding in-app purchase data handling.
