Apple Privacy Manifest Requirements

Apple mandates that app developers now specify approved reasons for API usage to enhance user privacy. By May 1st, 2024, it's required to include these reasons when submitting apps to the App Store Connect.

When using this specific plugin in your app, you must create a PrivacyInfo.xcprivacy file in /ios/App or use the VS Code Extension to generate it, specifying the usage reasons.

For detailed steps on how to do this, please see the Capacitor Docs.

For this plugin, the required dictionary key is NSPrivacyAccessedAPICategoryDiskSpace and the recommended reason is 85F4.1.

identifierstringThe identifier of the device as available to the app. This identifier may change on modern mobile platforms that only allow per-app install ids. On iOS, the identifier is a UUID that uniquely identifies a device to the app’s vendor (read more). on Android 8+, the identifier is a 64-bit number (expressed as a hexadecimal string), unique to each combination of app-signing key, user, and device (read more). On web, a random identifier is generated and stored on localStorage for subsequent calls. If localStorage is not available a new random identifier will be generated on every call.1.0.0
