Solution 1:

On a rooted phone, yes, it can access the shared preferences for your app. Also, on any phone the user can delete all the data that it's stored in shared preferences by clearing the cache in the application manager. A safe way to store data would be to encrypted it with AES and save it in a text file in the root folder of your app.
