In the Plans section of your account settings, click Select Plan next to the subscription option you wish to downgrade to. Your account will automatically downgrade to the selected plan at the end of your payment period and you should receive an email notification to verify.
If you wish to close your plan entirely, select Cancel Plan in the bottom right corner. This option will stop renewals your current subscription at the end of your payment period, at which time you will not be able to go live or access any content on your account.
If you are canceling your subscription, be sure to download any content you may need before your plan expires. You will not be able to access it when your subscription ends.
If you do not see the option to select a different plan or cancel your subscription, please either contact your account manager or complete this form.
