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 ~/.

Android: PlayerPrefs uses SharedPreferences . The data is saved in an XML file in the app's private folder, located at /data/data/pkg-name/shared_prefs/pkg-name. xml , where pkg-name is your application's package name.

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.

For instance, you could use JSON or XML to save game data in a structured format, and then read and write these files as needed. This method is more flexible and can handle complex data structures better than PlayerPrefs.
