I was under impression that by setting a visibility radius around my home address I'll hide any activity within that radius from the map. But it turns out that applies only to start and end of an activity. But what if someone stops by the home in the middle of a run or ride, for example to drink or refill water, or for any other reason? It turns out that is perfectly visible on the map if the activity is public.
The right solution would be to hide any part of activity from the map within the privacy radius - not just the start and the end.
