Hi, I recently found an Android app called 'Komoot', it seems to be using OSM data (for example it can't find certain house numbers which, coincidentally, aren't available in OSM, too) but OSM is not mentioned anywhere. Furthermore, you've to pay to 'unlock' certain regions, which means that you've to pay for OSM data. Stuff that's not even their own. How is that possible/legal?
