Even with the Lite app I would recommend blocking all or most of the app permissions before you run the app the first time. Otherwise Facebook will slurp up your contacts, texts, location, etc. You can block most of it since Android 6.0 by going into System Settings -> Apps -> Lite app -> Permissions -> turn everything off.
