Do I need to cancel after a 30-day free trial?

No.  Your credit card will automatically convert to your subscription plan.  We will send you an email near the end to let you know that your free trial is expiring and alerting you that your Genie Pro Subscriber status is being implemented.  If you do not wish to become a Subscriber, you must cancel your account to revert to a non-paid Member with limited access to all of Genie's tools.
