Hello ThePosiview,
Thank you for using Apple Support Communities! I understand that you would like to know if you have been charged for downloading an app. You would also like to know how to cancel the purchase and request a refund if you have been charged. I would be happy to help provide steps to take next.
Let's start by taking a look at your purchase history to confirm if you have been charged for this app:
See your purchase history in the App Store or iTunes Store - Apple Support
If the app offers a subscription, here's how to view if the subscription is active and cancel the subscription:
View, change, or cancel your subscriptions - Apple Support
The following support article will walk you through how you can request a refund for a purchase. It's important to note that you may not be able to request a refund for some recurring charges if this is a subscription-based service. In that scenario, I suggest contacting Apple Support using the link under step 4:
Request a refund for an App Store or iTunes Store purchase - Apple Support
Take care!
