public static string persistentDataPath { get; }

Remarks

This value is a directory path where you can store data that you want to retain between runs. When you publish on iOS and Android, 
persistentDataPath
points to a public directory on the device. The files can only be erased by users directly and not by any app updates. Note: The difference slashes indicate the different operating systems according to DirectorySeparatorChar.
When you build the Unity application, a GUID is generated that is based on the Bundle Identifier. This GUID is part of 
persistentDataPath
. If you keep the same Bundle Identifier in future versions, the application keeps accessing the same location on every update.
UWP Apps: Application.persistentDataPath points to 
C:\Users\<user>\AppData\LocalLow\<company name>
.
Windows Editor and Windows Player: Application.persistentDataPath usually points to 
%userprofile%\AppData\LocalLow\<companyname>\<productname>
. It is resolved by SHGetKnownFolderPath with FOLDERID_LocalAppDataLow, or SHGetFolderPathW with CSIDL_LOCAL_APPDATA if the former is not available.
Web: Application.persistentDataPath points to a location in the browser's IndexedDB file system. The path is formed as 
idbfs<hash>
, where 
<hash>
is an MD5 hash generated from the URL of the directory containing the application's web page. The specific filename (for example: 
index.html
) and any URL query parameters don't alter the persistent data path.
Linux: Application.persistentDataPath points to 
$XDG_CONFIG_HOME/unity3d/Company/ProjectName
, where 
$XDG_CONFIG_HOME
defaults to 
~/.config</c>. For example: <c>~/.config/unity3d/CompanyName/ProductName
.
iOS: Application.persistentDataPath points to 
/var/mobile/Containers/DataApplication<guid>/Documents
.
tvOS: Application.persistentDataPath is not supported and returns an empty string.
Android: Application.persistentDataPath points to 
/storageemulated<userid>/Androiddata<packagename>/files
on most devices (some older phones might point to location on SD card if present), the path is resolved using android.content.Context.getExternalFilesDir.
macOS Editor: Application.persistentDataPath points to 
~/Library/Application Support/company name/product name
.
macOS Player: Application.persistentDataPath points to 
~/Library/Application Support/unity.company name.product name
, but uses the Editor path if that directory already exists.
Saving files to this path: Some Unity APIs (for example, ScreenCapture.CaptureScreenshot) interpret relative paths as relative to the project directory on Windows Editor and other non-mobile platforms, not relative to 
persistentDataPath
. Therefore, screenshots or other files saved with a relative path end up in the project folder, not in 
AppData/LocalLow
on Windows. To save files to the persistent data path, pass a full path: 
System.IO.Path.Combine(Application.persistentDataPath, "filename.png")
.
