That depends on which subscription option you choose. You can choose to pay month-to-month, or once a year. If you choose to pay monthly, you’ll be charged on the same date each month (i.e. if you sign up on March 3, you will be charged on the third of each month going forward). If you choose the annual option, you will only be charged once a year for a full 12 months of use. We do offer a discount for signing up for the annual option.
