I need to know how to make the sure that the spades plus app doesn’t take anymore money from my account

This support article explains how to cancel a subscription from Apple on an Apple mobile device, Mac, PC, and online ➔ If you want to cancel a subscription from Apple - Apple Support or this video will only tell you how to do it on an iPhone ➔ https://www.youtube.com/watch/XXx-J-ueCtE

Notes:

• You might need to scroll down to find the Cancel Subscription button.

• If you don’t see Cancel Subscription, then the subscription is already canceled and won't renew. An "Expires" date (instead of "Renews") means the current subscription will just run until then. "Resubscribe" is just in case you change your mind about having it end.

• Deleting an app does not cancel a subscription.

• If you don’t cancel trials more than 24 hours before your renewal date, your subscription might renew.

• If you don't have an Apple device, see the options near the bottom of the support document.

• Many subscriptions are set to renew automatically until you intentionally cancel them.

You could delete it off your phone.

You could also use Screen Time to make it harder to spend any money on in-app purchases.
