This sounds sort of similar to Strava Flybys[0]. It users your run/ride location data and show people who posted public activies that passed you by. Sometimes interesting, but I bet a lot of Strava users who post their activities as "public" don't know this feature exists and might turn to "followers only" if they did.

- infamousclyde 4y agoThe Flyby feature has been opt-in for about two years.
- oakesm9 4y agoAh! Good to know. I didn’t see any reference to that on their product page so assumed it was still on by default
- ydant 4y agoIt's carved out as a specific permission on the privacy page now - https://www.strava.com/settings/privacy https://www.strava.com/settings/privacy - and also explicitly mentioned as turned off for "only you" activities, but no mention if it's exposed if your activity is "followers only".
- ydant 4y agoThis existed as a massive data-leak for a really long time. The "API" didn't have any meaningful protection, and the service was opt-in. It was really easy to download flyby exports for any activity and do analysis. I had a script downloading my Strava recordings of my commute and the associated fly-by data and was easily able to figure out all of the people I was seeing on the way to/from work. Since it linked to the activities and included profile pictures and names, you could easily figure out a lot. If I remember correctly, you could still see fly-bys of other peoples' rides even if your own was private or followers-only. It was a pretty massive oversight for a company like Strava - and a bit of an eye opener for me about what kind of data I might be leaking by making "harmless" activities like riding my bike into public data.
