It would be helpful to have the option to hide the start and end of the activities by GPS coordinates or manually selecting from a map, rather than using the postal address (city, street, number, etc.). This way, people like me that live outside cities and villages would have the option to hide their house's location.
In my case, for example, I live outside a village and the road that leads to my home (and some others in the surroundings) does not have any name, postal address service, or anything. So I only have the option to hide all activities start and end, or simply hide a lot of kilometers from the last known address. Which of course would do the job, but with the first one I would lose the possibility to show people where I start routes in the mountain, and with the second I would lose a lot of Strava segments near my home.
