content: If I understood correctly, they store the audio recordings indefinitely, just like all these other spies, I mean "assistants." You can even listen to them back from Amazon's servers it seems.   Amazon keeps all of the recordings of you asking Alexa to play WNYC or of you setting a timer..... You can jump into the Alexa companion app and hear all of your requests again if you want to see just how bored you sound when talking to your home voice robot. Sure, it’s slightly creepy — but Amazon also tracks pretty much every move you make while you’re online shopping as well.
