All our paid subscriptions are debited in advance, that is, we bill you at the start of each period.

If you're paying monthly we'll debit your card on the first day of your subscription, and then one month later, we’ll bill you for the next month! Same goes if you're paying yearly - we'll debit your card on the first day of your subscription, and then one year later, we’ll bill you for the next year.

This will go on until you choose to turn off automatic-renewal or the world ends, whichever comes first! 

P.S. You can see your next payment date under the Billing tab in your Settings. Too easy.
