They’re also what 99% of their users use so they really meed to have feature parity on important things like privacy, especially given how trivial this would be (“fuzz n meters from my current location”).
Interestingly, this feature is one of the first I recall using on Android maybe 8 years ago. It was very visible and easy to turn on... Not sure why they made it harder to discover. Or have they removed it?
They do offer manual route trimming from both ends, too. I've found this useful mostly when I forget to turn off my watch after running.
I’d believe it needed work after a major rewrite and is still in someone’s backlog. They seem to have a fairly small dev team - probably busy with device support & other time-sinks.
I wish they had a way to do an auto-trim so my bike rides didn’t include GPS bounce leaving the building. CommuteMarker.com had auto-tagging for Strava rides but not auto-trimming last time I looked.
If you go to the Privacy section of the iOS app it's mentioned at the bottom with a link to the webpage ("Further customise your privacy..."). Not ideal you can't do it from within the app though.
They do have the counter pressure of not losing users or inspiring government action. I’m not sure how this plays, for example, with the EU data protection laws but I’d bet there are some smart lawyers looking at this.
Strava apps are not perfect; they have a lot of settings in weird places. To sync with an ANT+ or Bluetooth sensor on Android you have to actually start recording an activity, and then press the small "settings" button in that page. Those settings are different than the ones in the main "settings". And then you add your HR sensor, record heartrate data for your workout and at the end you find that if you want it displayed in the app you have to pay :).
