Without asking permission, Google sends developers the personal details of everyone who buys their app from Google Play.
According to Australian developer Dan Nolan, Google sends him the name, suburb and email address of consumers that his app - enough to "track down and harass users who left negative reviews".
Nolan discovered the trove of customer data on his "merchant account" recently while updating his seller payment details.
Well, that's ridiculous. Luckily it's just name, suburb, and email address. >_> I wonder if this info deletes itself after a certain amount of time (i doubt it). Or if you can download it to sell.
