How do I stop sharing Fitbit data with Sensable Health when I am no longer a program participant?

When a user consents to share data with an application, those applications are listed in their Fitbit.com profile settings under “Applications”: https://www.Fitbit.com/settings/applications

Here you can see the name of the application (Sensable Health), the type of data they agreed to share, and the ability to revoke access to sharing data with the application.
