I’m Jennifer Valentino-DeVries, a tech reporter on the NY Times investigations team that uncovered how companies track and sell location data from smartphones. Ask me anything.
Your apps know where you were last night, and they’re not keeping it secret. As smartphones have become ubiquitous and technology more accurate, an industry of snooping on people’s daily habits has grown more intrusive. Dozens of companies sell, use or analyze precise location data to cater to advertisers and even hedge funds seeking insights into consumer behavior.
We interviewed more than 50 sources for this piece, including current and former executives, employees and clients of companies involved in collecting and using location data from smartphone apps. We also tested 20 apps and reviewed a sample dataset from one location-gathering company, covering more than 1.2 million unique devices.

Thank you all for the great questions. I'm going to log off for now, but I'll check in later today if I can.
