With the monthly plan you’ll get billed monthly for a price of 19$. With the annual plan you can pay your subscription once per year for 69$ (this is 5.84$ per month). If you decide to buy the annual plan you would spend 4 times less than purchasing a monthly plan every month. With both the plans the auto renewal will be active, so please deactivate it in your account settings if you don’t want to get charged when your subscription expires.
