Is it possible to cancel the free After Effects (Ae) abo after 7 days?

As an example with Netflix you can use a 30-day free subscription, but can cancel after the 30 days so that no costs are incurred. Is it at the Ae abo synonymous so that you can cancel after the 7 days and you therefore have to pay anything or give you only the first 7 days for free and then you have to pay for the subscription?

You can test for 30 days without completing a subscription, or not? At least I think so.

Their website only offers a 7-day subscription

You can test the program for 7 days without completing anything, this is not a subscription but just a trial.
