Watch out for this one. I really don't want them tracking my web visits and emails.

Even more reason to be careful in all your dealings with any of Google's services (Chrome, YouTube, Gmail, Sketch-Up, and many others). It's unbelievable how many services are Google owned or connected.  Big brother is watching and you're foolish if you don't think so. Best bet is to at least change your default search engine settings to a service other than Google.
