2. Yearly Plan
A yearly plan gives you access to the products and services as soon as your payment is processed. You'll be charged the annual rate stated at the time of purchase in one lump sum, plus applicable taxes. Your yearly plan will renew automatically on your annual renewal date until you cancel. Renewal rates are subject to change, but you will be notified of any change in your rate with the option to cancel under these terms.
