So, if you don't use the android app and don't use it's private messaging system for actually private stuff, you are just as "safe" as a non-user (since they can track you over websites with like buttons just as fine).
Also don't upload photos, don't put demographically-targetable keywords in any posts, don't let anyone tag you in photos, don't use Facebook to RSVP to events, and basically don't use the site at all, then yes.
