You can certainly install malware or something like a toolbar that may do nefarious things.. data and ad profiling are the cost of free it seems. Google could vet the apps but they won’t. I’m sure census demographics and your address are predictive enough for a lot of marketing and business related activities. You can also do the hyper ad targeting based on people who live in X and at what age. So the voter profile of CA may not have been specifically more useful than voter registration and demographics. Using Facebook and YouTube was essential though. That allowed them to optimize the content campaigns with real-time feedback.
