What does Parental Control do in Fortnite?

I wanted to ask what Parental Control controls everything, such as maximum play time, purchases, etc. Please only those who know, thank you!

Think that is very individual because certainly not all parents take this right…

You can enable this ingame separately, so that the younger players do not know what I do in Fortnite, that's why I ask

Aha Find nothing on the Internet except that you can disable the function for purchases.
