When I had paid apps in the Play Store, I used to be able to see the purchaser's email address and general location (city, zip) of the purchaser--no names, though. That was only true for paid apps--there was (is) NO information returned to me for free apps.
I can't see that information now in my Developer Console since I'm guessing since I pulled the paid apps and only left the free versions out "there".
Cheers!
