But it is perfectly normal to try to lower the risk of getting sued, even if the chance will never be zero.

FYI, from the FAQ:

Why is Magic Earth free? What is the business model?

Magic Earth is free for all our end-users but we also have a paid Magic Earth SDK for business partners. For instance Selectric.de (a supplier for navigation solutions for ambulances and fire trucks), Smarter AI (developing ADAS systems) or Absolute Cycling (using the platform on bicycles). For more info on the SDK, you can check magiclane.com.

No web interface?

I agree. For now, as I find everything to be a bit too big, I put the zoom at 90% in my browser.
