To prevent the App Store from charging you for AI Mirror after a free trial, you need to cancel your subscription before the free trial period ends. Here are the steps to cancel a subscription on your iPhone or iPad:
1.Go to the "Settings" app on your device.
2.Tap on your name at the top of the screen, then select "Subscriptions".
3.Select the subscription you want to cancel.
4.Tap "Cancel Subscription" and follow the prompts to confirm the cancellation.
If you cancel a subscription during a free trial period, you will still have access to the subscription until the end of the trial period. However, you will not be charged for the subscription once the trial period ends.
