While Using App
This option is actually sufficient to operate Logbook App. Everything works as designed when you're in the App. However, enabling autorecording and leaving the App will show a blue ribbon on the top indicating Logbook App is still running and accessing the locatino in the background.
The blue ribbon is no longer visible, however Logbook App is still only using your location data in background if autorecording is enabled.
