Astra Development ("we", "our", or "us") operates the MP3 Player & Audio Music Mixer mobile application (the "App"). This Privacy Policy explains how we collect, use, and protect your information when you use our App.
Audio Files: The App stores your imported music files locally on your device. Audio files are never uploaded to our servers or any third-party service.
Music Library Data: Song metadata (titles, artists, album names, playlists, play counts) is stored locally on your device using SwiftData. This data is never transmitted externally.
Purchase Information: If you subscribe to our premium features, purchase transactions are handled entirely by Apple App Store. We use RevenueCat as a payment processor to manage subscriptions. We do not store your payment details.
WiFi Transfer: When using the WiFi Transfer feature, a local HTTP server runs on your device to receive files from your computer. This connection is local (same WiFi network) and no data passes through our servers.
All music files, library metadata, playlists, equalizer settings, and preferences are stored locally on your device. We do not collect, transmit, or store any of your data on external servers.
The App uses the following third-party services:
The App does not collect analytics, usage statistics, crash reports, or any personal data. Your music library and listening habits remain completely private on your device.
The App is not directed to children under 13. We do not knowingly collect personal information from children under 13.

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
