Your Apps Know Where You Were Last Night, and They’re Not Keeping It Secret
If there’s one thing that has made smartphones the gamechanging tech of our lifetimes, it is the use of location data – think Amazon’s delivery efficiencies or ride sharing or food delivery, etc. Whilst all these are examples of how businesses and consumers alike have benefited from the technology, there is a dark side to it. In this superb piece of journalism, the authors of this interactive article, show how information about our whereabouts is not just being recorded but also sold as ‘insights’ thanks to our smartphones hanging onto our person all the time and the several apps whom we have knowingly or otherwise allowed to access, store and share our location data.
“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 Times found. Several of those businesses claim to track up to 200 million mobile devices in the United States — about half those in use last year. The database reviewed by The Times — a sample of information gathered in 2017 and held by one company — reveals people’s travels in startling detail, accurate to within a few yards and in some cases updated more than 14,000 times a day.
These companies sell, use or analyze the data to cater to advertisers, retail outlets and even hedge funds seeking insights into consumer behavior. It’s a hot market, with sales of location-targeted advertising reaching an estimated $21 billion this year. IBM has gotten into the industry, with its purchase of the Weather Channel’s apps. The social network Foursquare remade itself as a location marketing company. Prominent investors in location start-ups include Goldman Sachs and Peter Thiel, the PayPal co-founder.
“To evaluate location-sharing practices, The Times tested 20 apps, most of which had been flagged by researchers and industry insiders as potentially sharing the data. Together, 17 of the apps sent exact latitude and longitude to about 70 businesses. Precise location data from one app, WeatherBug on iOS, was received by 40 companies. When contacted by The Times, some of the companies that received that data described it as “unsolicited” or “inappropriate.”
Most users whilst having given permission to the app to access its location data are not completely aware of what they sign up for.
“Ms. Lee had given apps on her iPhone access to her location only for certain purposes — helping her find parking spaces, sending her weather alerts — and only if they did not indicate that the information would be used for anything else, she said. Ms. Magrin had allowed about a dozen apps on her Android phone access to her whereabouts for services like traffic notifications. But it is easy to share information without realizing it. Of the 17 apps that The Times saw sending precise location data, just three on iOS and one on Android told users in a prompt during the permission process that the information could be used for advertising.”
Even industry insiders acknowledge that many people either don’t read those policies or may not fully understand their opaque language. Policies for apps that funnel location information to help investment firms, for instance, have said the data is used for market analysis, or simply shared for business purposes.
“Most people don’t know what’s going on,” said Emmett Kilduff, the chief executive of Eagle Alpha, which sells data to financial firms and hedge funds. Mr. Kilduff said responsibility for complying with data-gathering regulations fell to the companies that collected it from people.
