Is it necessary to give them location data to use the app?

They'll know through your IP.

they will know that this IP sent this much data to that IP but not what was inside it.

Your ISP knows the same when using a web site via HTTPS. They can see you send a request to the website but not what it contained.

You could also use a VPn or TOR if you want to hide your IP.

And they'll know who you contacted and when. That allows for a lot of things to be guessed. Especially with hundreds of thousands of messages per user available to them.

Yeah, but my ISP has to follow the local laws and I can easily switch ISPs if I dislike my current one. Try that with Facebook.

Yeah, I might use a VPN but I'd also have to force all my contacts to use one as well.
