Licensing & Attribution

Every source the app carries, and what each one asks to be called

Corridor ships its maps rather than fetching them, so it redistributes the sources below inside the app. The lines in monospace are the wording each licence asks for. The same list is on the licensing screen inside the app, from the same file.
