Video to MP3: MP4 Converter (shown in the app as Audio Extractor) is built to keep your media private. The app does not collect, transmit, or sell any personal data.
Nothing. The app has no account system, no analytics, and no advertising or tracking SDKs, and there is no server of ours that receives your data. Our App Privacy declaration on the App Store is "Data Not Collected."
Videos and audio files you choose are read and converted entirely on your device using Apple's AVFoundation framework and a bundled open-source MP3 encoder (LAME). Your files are never uploaded to any server, and conversion works offline. Converted files stay in the app's temporary storage on your device until you save or share them; they leave your device only through the destination you pick in the share sheet.
When you pick a video or file, iOS shares only the items you select through the system picker. The app does not browse your library and requests no standing photo-library, camera or microphone permission. If a selected video is stored in iCloud Photos, iOS may download it from your own iCloud before the app can read it.
The app keeps a few preferences on your device, such as whether you have completed onboarding and a count of exports. These are not sent anywhere by the app.
Purchases are handled by Apple through StoreKit. We never see your payment details. Apple processes purchase data under its own privacy policy. Apple is the only third party the app works with.
