You're 100% right. That questions is framed to be impossible. Completely unfair. Bad H2SO4.

There no way to know what type of data each comp... oh wait... you could compare this:
http://www.apple.com/legal/privacy/en-ww/ to this :
http://www.google.com/policies/privacy/
Spoiler alert: you're going to find basically the same information. Google even adds pop overs to further explain some of the terminology both companies use. Apple uses your data to, among other things, serve ads.

Just.Like.Google. I know this to be true because Apple says so.
