From amazons terms and agreement.

"Any app that has Amazon DRM applied to it will require users to have installed and signed-in to the Amazon Appstore client to access the app. When an app is accessed by the user, it will verify with the Amazon Appstore device service as to whether the user has an entitlement to the app. If the user does not sign in or does not have an entitlement to that app, then the app will not be usable. However, any user can gain an entitlement by purchasing the app through Amazon."

What is not stated above is how they do it. Amazon uses an offline tolken key to decrypt the DRM. For the most part things run smooth until you are logged out, as I was, or the tolken key is corrupted.
