Cancel my app subscription

I did the Premium Subscription with 1 week free. I have tried to cancel through my apps on my I phone but can't figure it out.  Under Edit Subscription it says Fing- Network Scanner Premium Subscription Premium 1 Month Free 1 Week. Then It says Options, under options it says Premium 1 Month (1 Month)-$6.99. Premium 1 Year (1 Year) $59.99. Underneath these in lighter print it says Select an option to resubscribe if you resubscribe , your new subscription will begin on Jan. 1, 2021. I need to know if this automatically cancelled already or do I need to do something to ensure it doesn't get charged to my account? Thank you for your help.
