Currently, we do not offer single-period purchase options and all subscriptions are auto-renewable. Once you proceed with a purchase, you’ll select a period of subscription and your plan will renew based on the period you selected. To avoid being charged for the next billing cycle, you must cancel your subscription at least 24 hours before the renewal date.
To view the details of your subscription, including the renewal period, follow the instructions below:
1. Open the Settings app.
2. Tap your name, then tap Subscriptions.
3. Tap the subscription that you want to view.
Here’s the Apple Support Guide on Managing Subscriptions.
