When canceling an annual subscription, users will incur an early termination fee equal to two months of service charges.
Those who use the Self Service Buy option can cancel their subscription. First log into AppDynamics.com, then navigate to the account page, and click on the subscriptions box.
From the subscriptions page, click the "Cancel Subscription" button.
Use the checkbox to accept the end user license agreement and click the "Cancel Subscription".
You will receive an email with the subject "Your AppDynamics Subscription Has Been Cancelled" as confirmation of your changes.
