GitHub user breautek added a comment to the discussion: Persistent storage
The user can clear **ALL** local storage. The browser's storage mechanisms (cookies, local storage, indexedDB) are all stored in the app's data directory. The file plugin exposes the ability to store files directory into the app's data directory, as well as some other directories. When the user uninstalls the app, or clears app storage, the OS will clear the app's data directories which includes all that is mentioned above. Short of controlling the data on a server and having the user to log into an account to relate that data to the user, it is impossible to guarantee persistent storage. Other options that doesn't involve a server: 1. Is to use a media store plugin to store files on the user's "external" filesystem inside the documents container. Other apps may be able to read these files so it's not suitable if storing anything sensitive. The user can still delete the file, but as long as you don't use an app-specific external storage, the files should be retained (90% sure...). Apache's file plugin has limited support for external storage since Android's SAF framework. It's not suitable for writing documents to external storage. Therefore a third-party plugin that interfaces with the native MediaStore APIs is required. 2. Use a plugin to integrate with user's cloud storage such as google drive. Naturally the user can still delete the data, and other apps may also be able to read that data. So it faces similar issues as using the external filesystem partition. But I don't believe the data is cleared on app uninstalls or explicit clear app storage requests since it's external to the app's data directories. Note that some jurisdictions, by law, you must provide some sort of mechanism to allow users to delete their data.
