Nanit violates in-app purchase regulation or not?

Hello there,

I'm using the app called Nanit for baby monitor. It provides advanced function called "Nanit insight" in the way of subscription. This function provides only digital service without any physical service.

However, as I click the button called "Start trial", it opens Safari and leads me to the new web page. In this page it requires me to fill in the information of credit card for further subscription after trial.

Is that legal in App Store? As I know, this should be In-App purchase and not allowed in opening web page for purchasing.

Thanks for answering !
