An app on the device gathered her location information, which was then sold without her knowledge. It recorded her whereabouts as often as every two seconds, according to a database of more than one million phones in the New York area that was reviewed by The New York Times. While Magrin’s identity was not disclosed in those records, reporters were able to easily connect her to that dot.
The app tracked her as she went to a Weight Watchers meeting and to her dermatologist’s office. It followed her hiking and staying at her ex-boyfriend’s home, information she found disturbing.
“It’s the thought of people finding out those intimate details that you don’t want people to know,” said Magrin, who allowed The Times to review her location data.
Like many consumers, Magrin knew apps could track people’s movements. But as smartphones have become ubiquitous and technology more accurate, an industry of snooping on people’s daily habits has spread and grown more intrusive.
