mapy.cz - How maps learn about traffic?

How mapy learn about current traffic? If I have app installed on the phone, does it help in any way? Or I should have app opened and in navigation mode?

I noticed that even I was driving one route, there was no information on the other device

It depends in what region. I know that in CZ they definitely get it through official government site that tracks closures, roadworks, traffic from monitoring cars and counting gates...

My 2 cents: they buy this data from TomTom. But I'm speculating here
