the tinder app, like pretty much all apps, is constantly calling graph.facebook.com while in use. Because the app doesn't work without Location access, FB gets a lot of rich location data every time the app is in use, but I don't believe the data being sent back can be utilized for fraud detection.

There's also calls out to crash-analytics, firebase, appsflyer and Google Analytics constantly. The app will function if all these services are blocked.
