You can add privacy zones around locations so when people look at your activities your line just disappears inside the radius of your privacy zones. I have ones around my home and where I work. No idea if that affects whatever data they sell (I doubt it, since you can still the full activity yourself even with a privacy zone), but stops people finding where you live/work and nicking your bike

The fact that an area is made private is also a piece of information. I was thinking that you could use that to track down sensitive areas.

  Unless I'm missing something you can easily triangulate the center point of the private area.

That’s effective on an individual level, but tricky to enforce at an organizational level. It’s not like it would be wise for the DoD to log into Strava and setup a privacy fence around every sensitive location.

you're essentially telling strava that the privacy area is very important to you (ie your home, work, etc) and they are probably selling that fact.

  What a great signal for thieves too - this user has enough disposal income to have a fitness device, and is worried about being tracked, they must have good stuff. Presumably you could filter by average speed and only get people with expensive bikes too.

    You could also tell who from the public data has a private area, how long they are in it and when they leave it. You could do graph analysis to find folks on 20k bikes (correlate by zipcode) traveling at > 20mph with other folks that also have privacy areas. If you find that > 3 of folks in that clique are close together and somewhere else, probably having a group event, many of them may not be in their "privacy area". Anything that collects your location data is a shtshow when it comes to operational security. Even having one friend with poor GNSS hygiene can expose an entire network of relationships.
