NEW YORK, April 22 (UPI) -- Apple's iPhone and Google's Android phone regularly track a user's location and send it back to those companies, raising privacy concerns, experts say.
The companies are gathering location information as part of their efforts to build massive databases capable of pinpointing where phone users are -- databases that could help them tap a market for location-based services expected to be worth $8.3 billion in 2014, The Wall Street Journal reported Friday.
