Not a big thing, I only noticed because while I don't track users at all I do check which domains make requests (via the origin header), so I saw yours and thought I'd check it out.

Good luck with the project! 👍

Hey, just letting you know that your usage of maps.black does not meet the openstreetmap license on at least the web version at walkbetter.mstf.fyi . You need to credit openstreetmap per the ODbL. I'm of course happy for you to use my service but please follow the licenses of the data providers.
