Subscriptions renew automatically whether you subscribed through JillianMichaels.com, iTunes or the Google Play Store. You may cancel your subscription to My Fitness anytime before your next billing date, meaning you turn off the auto-renewal for your subscription whenever you'd like. If you cancel at least 48 hours before your next billing date, you will not be charged for subsequent billing periods after that. If you do not cancel more than 48 hours before your next billing date, your subscription will be automatically renewed using the credit card information that is on file for your account. When you cancel, you will continue having access to your subscription through the end of the billing period you have already paid for.
Please note we do not issue refunds for cancellations that are requested after you have been charged.
