Write a ContentProvider for your free version that offers the data files to the requesting paid version. You should define a permission for your ContentProvider with protectionLevel=signature so no unauthorized third party app can request that data from your ContentProvider (you must sign the paid version with the same key though).
Implement the method public ParcelFileDescriptor openFile(Uri uri, String mode) in your ContentProvider for offering the files.
