Lacking proper attribution/myTrails

Violation of OpenStreetMap copyright

You are using OpenStreetMap based maps. I am happy to see work of me and other mappers used. And there are minimal requirements that you are obligated to fulfill - provide a clearly readable attribution (see https://www.openstreetmap.org/copyright )

(1) Unfortunately you are doing it without providing required attribution and you lie to your users.

(2) Mass download dialog contains the claim "this map may be used without any restrictions", what is untrue.

(3) Please review Tile Usage Policy, as likely you violate also this: https://operations.osmfoundation.org/policies/tiles/
