This app looks really great, but I have a few questions... (1) Where does the online map data come from? From Magic Earth servers or somewhere else? (2) Where is the 3D data sourced from? (3) Where is the satellite imagery sourced from? OSM definitely doesn't have this. (4) Where are transit directions sourced from? AFAIK OSM also can't do this. (5) Who is behind this app? The privacy policy just refers to them as 'Company'. All in all, the functionality looks great but I'm quite skeptical about the lack of transparency.
