How do I cancel my iTunes subscription?

Cancelling your iTunes subscription is simple and can be done on your Apple device.
The free trial and subscriptions may be managed by the user and auto-renewal may be turned off and cancelled by going to
your iTunes account settings after purchase.

1. Open the Settings app.
2. Tap your name.
3. Tap Subscriptions. (If you don’t see “Subscriptions,” tap “iTunes & App Store” instead. Then tap your Apple ID, tap View Apple ID, sign in, scroll down to Subscriptions, and tap Subscriptions.)
4. Tap the subscription that you want to manage.
5. Tap Cancel Subscription. If you don’t see Cancel Subscription, the subscription is already canceled and won’t renew.

This must be done 24 hours before the end of a free trial or subscription period to avoid being charged.

The cancellation will take effect the day after the last day of the current subscription period. Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription during
the free trial period.
