PlayerPrefs is a class that stores Player preferences between game sessions. It can store string, float and integer values into the user’s platform registry.
Unity stores PlayerPrefs in a local registry, without encryption. Do not use PlayerPrefs data to store sensitive data.
Unity stores PlayerPrefs data differently based on which operating system the application runs on. In the file paths given on this page, the ExampleCompanyName and ExampleProductName are the names you set in Unity’s Player Settings.
Standalone player and in-Editor Play mode storage location
- MacOS: ~/Library/Preferences/com.ExampleCompanyName.ExampleProductName.plist
Standalone Player storage location
- Android: /data/data/pkg-name/shared_prefs/pkg-name.v2.playerprefs.xml. Note that C#, Android Java and native code can all access the PlayerPrefs data.
- iOS: Uses the [NSUserDefaults standardUserDefaults] API to store PlayerPrefs data.
- Linux: ~/.config/unity3d/ExampleCompanyName/ExampleProductName
- WebGL: Unity stores up to 1MB of PlayerPrefs data using the browser's IndexedDB API. For more information, see IndexedDB.
- Windows: HKCU\Software\ExampleCompanyName\ExampleProductName
- Windows Universal Platform: %userprofile%\AppData\Local\Packages\[ProductPackageId]\LocalState\playerprefs.dat
In-Editor Play mode storage location
- Windows: HKCU\Software\Unity\UnityEditor\ExampleCompanyName\ExampleProductName key. Note that Windows 10 uses the application’s PlayerPrefs names. For example, Unity adds a DeckBase string and converts it into DeckBase_h3232628825. The application ignores the extension.
