On iOS at least, a lot of these (location, contact info, health & fitness, etc), you can deny access to via a popup prompt when the app tries to access them.
It’s a Meta app though so at a bare minimum it’s absolutely going to track the heck out of how you use the app.
I don't know about this particular app, but if I remember right, for a while blocking these requests would actually cause the app to break completely. I'm sure it had nothing to do with the permissions being needed but primarily just to punish people who didn't give them access to their data.
