I don't think the actual application-specific events would be used by Google - as every application has their own events and ways to use them there would be no generalized way to do it without having developers manually "reverse engineer" the event meanings and assign them to ad targeting signals.

What Google most likely does however is use persistent analytics IDs to track people and improve their on-site tracking. Let's say you clear your cookies and happen to change IPs (dynamic IP, etc) so you appear to Google's web properties as a new user - all they have to do is wait for some other piece of software on your machine to report analytics with a persistent ID and essentially bridge the gap between your old identity and your new one, so now just based on IP alone, Google's web properties can infer with good accuracy (and the more datapoints the higher it goes) that it's you.

This is EXACTLY what I, and I believe MANY other people
