@pierre-yves-colle I agree about indoor activities and I have never experienced such behaviour.
I use my s9 not only for the mountains - actually I must skip summer season each year because of uni. But I go skating in the neiborhood or just for longer walks, so over time the routes overlap enough for a curious mind to decifer my location. There is a suggestion in the forum btw to limit displayed maps and have a private circle in predifined locations, feel free to vote for that, if you find it useful.
