Summary
FourThirtyTwo processes your audio on your device. The app does not send your audio files, settings, library data, or usage activity to FourThirtyTwo servers.
What the app stores locally
To work correctly, the app stores some information on your device:
- Settings such as your default tuning, export format, and haptics preference.
- Imported audio access information, including security-scoped bookmarks when you choose files from the Files app.
- Temporary imported files, extracted ZIP contents, and rendered conversion files in the app's cache directories.
- Library audio files and library metadata if you choose to save converted tracks to the in-app library.
- Track metadata you edit or keep with saved items, such as title, artist, and album.
What the app does not do
FourThirtyTwo does not create user accounts, does not use third-party analytics SDKs, does not upload your audio to developer-controlled servers, and does not sell or share your personal information.
Debug logging
The app writes debug and error messages to Apple's on-device system logging facilities to help diagnose problems during development and troubleshooting. These logs are not transmitted by the app to FourThirtyTwo servers. Some log entries may include file names, track titles, timing information, or error details. File paths are intended to be logged with private redaction where applicable.
Your control
You can remove cached renders from Settings, clear the in-app library from Settings, delete library items individually, and remove the app to delete its local app container data from your device, subject to iOS behavior and any device backups you control.
