NyanD,

' So what i tried to say is facebook is tracking user data or google is giving my data to facebook? .. Can anyone help me confirm this?'

I'm unable to confirm it based on my own experience with Facebook. I'm one of the small minority of those who don't have a Facebook account. (That's even IF a minority exists!)

With the above said, you should be able to find the answers you're looking for by reading the below:

Best of luck..
