You get that data for "free" or your hand over your browser data - and likely location data, to unknown third party brokers that know more about you than you know about yourself. Weather apps in particular are notorious for selling your location data, since everyone does "show weather for my current location".

It's "free" in the worst sense of the word.

Do you know much about Windy, and whether they have any ties to selling user location data?

All the plots and features seemed nice so I paid for a year of subscription (after Dark Sky was discontinued ugh), but if they do that I’ll just stick to the default apple Weather app.
