You can cancel your auto-renewable subscription from the Settings app of your iPhone or iPad.

1. Go to Settings > iTunes & App Store.

2. Tap your Apple ID at the top of the screen.

3. Tap View Apple ID. You might need to sign in or use Touch ID.

4. Under Subscriptions, tap Manage.

5. Tap the subscription that you want to manage.

6. Use the options to manage your subscription. You can choose a different subscription offering, or tap Cancel Subscription to cancel your subscription. If you cancel, your subscription will stop at the end of the current billing cycle.

The subscription automatically renews if it is not cancelled within 24 hours before the end of the current subscription period. Your account will be charged for the next subscription period up to 24 hours prior to the current subscription expiring. It is not possible to cancel an existing in-app subscription. You can disable the automatic renewal function at any time by adjusting your account settings.
