Your Location is For Sale

I have written before about how our smartphones are ratting out our location, using GPS and even just cell tower location information.  The New York Times recently published a story that followed a woman throughout her day and discovered that her location was collected over 8000 in a single day.  From the location database they purchased from a location data broker, they were able to track her from her home, to the school she worked at, then on to a Weight Watchers meeting, a doctor’s office, a dog-walk, and an overnight stay at her boyfriend’s house.

This location data is collected by almost every smartphone app you have on your phone, including apps like GasBuddy and The Weather Channel.  This information is sold to information brokers, and purchased by retailers, marketers, and even lawyers and doctors looking for new clients.

For example, over the holidays, I signed up on SnapChat because my son said that’s where our grandson’s pictures will be.  SnapChat wanted access to my location (of course), my contacts and my pictures and videos, and the ability to send and read SMS messages.  This app also seems to be another online rabbit-hole, where the pictures go in but cannot be saved elsewhere.  I am not liking that feature either.  What if Snapchat goes belly-up?  How do I get those pictures of my grandson?

There are at least 70 companies providing this information, and they are collecting it from hundreds of app developers.  Thought that free app was free?  They can make more money selling your location information than they could selling the app for $5 per user.

The Times detailed methods to defeat or disable location tracking on Android and iPhones, but basically you need to get into Settings, Privacy, Location, or Security and Location.  You will also need to disable location on the individual apps as well.  My advice is to be stingy when an app asks to share location or other information.  Say NO unless it is absolutely necessary.

The good news is that ATT and Verizon have recently announced that they will no longer be selling location data.  This does nothing to prevent app developers from selling the information they are collecting.  Senator Ron Wyden of Oregon is trying to legislate our way out of this mess, but this is a $12 billion dollar business and I have doubts that any legislation that might solve this problem will ever make it through Congress.
