The Speakin' Ilonggo app (both the free version and full version) does not transmit any user data or external data to or from the device. All app data (audio files, images) are included in the install and all user data (progress, preferences) are stored and used only on the user's device in the app's temp data. A previous version of this app stored users' email information in order to verify if a user purchased the full version, thereby allowing free and full version features to be contained in a single app. This is no longer the case as there are now two seperate versions (free and full) that are both entirely functional offline. Please feel free to contact me if you have questions. Paul Soderquist paulsoderquist3@gmail.com
