In some cases we offer a 7-day free trial with our yearly plan. If this is applicable to your purchase, this will be shown in detail during the checkout process.
If you signed up for a trial, you are under no obligation to stay for the whole year and will not be charged until the 7-day free trial is over—just subscribe, learn to your heart’s content, and cancel any time before your 7 free days have passed.
For the steps on how to cancel your trial or subscription, check out this article.
Please note that you may only start a trial once: if you've previously purchased a subscription and made use of the 7-day trial already, you won't be able to start a new trial the next time you sign up for a yearly subscription.
