The first 30 days of Cc are completely free. If you do not cancel your Cc Pro subscription before your trial has ended, then your card will automatically be charged 30 days after signing up for Cc Pro.
Once your 30 day trial is over, Cc will continue charging your card on the billing schedule you chose until you cancel your Cc Pro subscription. If you chose the monthly version of Cc Pro, your card will be charged every month. If you chose the annual version of Cc Pro, your card will be charged only once a year. Remember, you can always cancel at any time.
