Probably not surprising of course, but is it generally legal?

Question

Facebook

Been trying unsuccessfully for a while to get through the SSL Pinning of the Facebook app. I wanted to get access to a private api. After some time, I managed to do it. After playing around, I noticed that every minute Facebook sends itself requests of this kind. I did not attach any importance to this, but after considering all the transmitted data, I was a little shocked. Wifi network name, network quality, internet speed, my SIM card details, operator name, towers, etc. Here and GPS is not needed to understand exactly where I am. What kind of beard is that? Do they have any right to do so?
