Stores and accesses player preferences between game sessions.

Editor/Standalone

On Mac OS X PlayerPrefs are stored in ~LibraryPreferences folder, in a file named unity.[company name].[product name].plist, where company and product names are the names set up in Project Settings. The same .plist file is used for both Projects run in the Editor and standalone players.

On Windows, PlayerPrefs are stored in the registry under HKCU\Software\[company name]\[product name] key, where company and product names are the names set up in Project Settings.

On Linux, PlayerPrefs can be found in ~/.configunity3d[CompanyName]/[ProductName] again using the company and product names specified in the Project Settings.

WebPlayer

On Web players, PlayerPrefs are stored in binary files in the following locations:

Mac OS X: ~LibraryPreferencesUnityWebPlayerPrefs

Windows: %APPDATA%\Unity\WebPlayerPrefs

There is one preference file per Web player URL and the file size is limited to 1 megabyte. If this limit is exceeded, SetInt, SetFloat and SetString will not store the value and throw a PlayerPrefsException.
