There is a one-time charge for the total amount that you will see on your credit card. Once you pay, you will receive the license key that you can use for one year. There is no recurring charge or an automatic renewal of the license key. If you would like to renew the license key after one year, you may do so by clicking on the Renew Now button in the bottom left side of the program screen. This link will be available starting from 30 days before the key expires.
