How Facebook tracks you on Android (even if you don't have a Facebook account)

I think I’ve read someone’s thread saying that FBI is warning about smart TV’s security. I’ve just chanced upon this article online. Even Facebook can tracks you on android! Omg! This is amazing and scary on the other hand.

The way technology companies collect our data is getting crazier… :pensive:

Ikr. Facebook collects billions of data points everyday! Wonder how much they earn from it.

Search engine like brave or boogle, would be a better choice in this age.
