New strife for Strava: location privacy feature can be made transparent

But as Wandera's Liarna La Porta wrote, the privacy zone might not be enough: “If an activity on Strava is circular in nature and the return route is from the opposite direction, it is relatively easy to deduce the mid-point and where the privacy zone is centred on. If there are not two exact opposite points, it’s possible to use a third point from a different activity and solve the equation of a circle passing through 3 points.”

Previously, Strava had published heatmaps generated from 13 trillion GPS coordinates from joggers' data, which inadvertently exposed the locations of military bases around the world, including those in the U.S.
Exposes full name, picture, running routes of strangers
This week, Andrew Seward, Head of Data Product Development at Experian, brought to light how Strava exposed sensitive information on nearby runners.

"Out running this morning on a new route and a lady runs past me. Despite only passing, when I get home Strava automatically tags her in my run," tweeted Seward.
"If I click on her face it shows her full name, picture and a map of her running route (which effectively shows where she lives)," he continued.

Shortly, Seward showed that many of the app's privacy settings defaulted user information visibility to "Everyone."
