Instead of writing out the list, which is extensive, on ways google gathers data let me give you an example of how NOT private the internet it.
Lets take this very post I'm writing as an example.
Even if there wasn't a +1 button down there most sites have SOMETHING Google. A search box, analytics, adsense, a 3rd party tracking system which shares data... the list is long.
