Description

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.

Notes:

- 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 uses the key names from the application’s PlayerPrefs as a hashed identifier. For example, Unity adds a DeckBase string to the hashed key name (for example h3232628825) to create DeckBase_h3232628825. Unity hashes the names because it:

  • Allows Unity to store case-sensitive key names.
  • Prevents naming conflicts with data the application stores outside of PlayerPrefs.
  • Ensures that you use the PlayerPrefs API to access and modify the values.

The application ignores the extension.
