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.

Interfaces

DeviceId

Prop	Type	Description	Since
identifier	string	The 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

DeviceInfo

Prop	Type	Description	Since
name	string	The name of the device. For example, "John's iPhone". This is only supported on iOS and Android 7.1 or above. On iOS 16+ this will return a generic device name without the appropriate entitlements.	1.0.0
model	string	The device model. For example, "iPhone13,4".	1.0.0
platform	'ios' | 'android' | 'web'	The device platform (lowercase).	1.0.0
operatingSystem	OperatingSystem	The operating system of the device.	1.0.0
osVersion	string	The version of the device OS.	1.0.0
iOSVersion	number	The iOS version number. Only available on iOS. Multi-part version numbers are crushed down into an integer padded to two-digits, ex: "16.3.1" -> 160301	5.0.0
androidSDKVersion	number	The Android SDK version number. Only available on Android.	5.0.0
manufacturer	string	The manufacturer of the device.	1.0.0
isVirtual	boolean	Whether the app is running in a simulator/emulator.	1.0.0
memUsed	number	Approximate memory used by the current app, in bytes. Divide by 1048576 to get the number of MBs used.	1.0.0
diskFree	number	How much free disk space is available on the normal data storage path for the os, in bytes. On Android it returns the free disk space on the "system" partition holding the core Android OS. On iOS this value is not accurate.	1.0.0
diskTotal	number	The total size of the normal data storage path for the OS, in bytes. On Android it returns the disk space on the "system" partition holding the core Android OS.	1.0.0
realDiskFree	number	How much free disk space is available on the normal data storage, in bytes.	1.1.0
realDiskTotal	number	The total size of the normal data storage path, in bytes.	1.1.0
