An investigation by The New York Times has found that many smartphone apps receive data on a user’s precise location thousands of times per day. “As smartphones have become ubiquitous and technology more accurate, an industry of snooping on people’s daily habits has spread and grown more intrusive,” it writes. “At least 75 companies receive anonymous, precise location data from apps whose users enable location services to get local news and weather or other information.”
The obvious solution is to deny the app your location. Or make one up, if given the option.
