Snapchat’s newest feature is also its biggest privacy threat

Earlier this week, Snapchat introduced Snap Map, an opt-in function that allows you to share your location with your friends on a map. Snapchat’s introduction video to Snap Map, seen above, focuses on sharing the location of posted Snaps to Our Story, which is public, and could be useful for, say, seeing a collection of Snaps from a particular event.

But what Snapchat doesn’t tell you in the video, or in the app, is that if you aren’t careful, Snap Map will broadcast your exact location to anyone on your friends list every time you open the app.

When you update Snapchat and get to the Snap Map walkthrough, as seen below, only three screens need to be clicked through to complete it. Though it mentions sharing your location, it’s vague on what that exactly means. Users might not understand that Snap is posting your location on Snap Map every time you open the app. Not just when you share Snaps to Our Story.

When I first opened Snap Map, I saw the Bitmoji for one of my friends in a residential area. I presumed this was her home, and was able to zoom in close enough to estimate where she lived on that particular block. Then I called her. “This is a weird question,” I said, “but do you live at the intersection of X and Y? More particularly, one of these addresses?” I rattled off three house numbers on the street closest to where her Bitmoji appeared on Snap Map. One of them was correct. I’ve never been to her house.
