Section 1.1 of the Alexa Calling and Messaging Schedule (at the bottom of those terms) seems to imply that the actual content of your calls isn't what they call "Alexa Interactions", although if you call out to Alexa during the call ("Alexa, hang up"), that is an Alexa Interaction.

It's not very clear, though, and I feel like they could have made this clear very easily.

(I do expect Amazon to store the voiceprints of "Alexa, do foo" to improve their speech-to-text, as well as analyze the actual requests, yes, but I would hope that Amazon is not analyzing or storing the contents of calls.)
