What are auto-renewal and non-auto renewal?

Auto-renewal:

If you select "Auto-Renewal" when choosing a premium plan, after confirming the purchase, the subscription fee will be charged from your iTunes account. Subscription is automatically renewed unless you turn it off 24 hours prior to the end of the current period. It is usually cheaper.

 

Non-auto renewal:

If you prefer non-auto renewal, you won`t be charged when your premium expires.
