Did you know that Alexa is always listening? Alexa listens for your “wake” word, the phrase that tells the device to start doing something. When you say Alexa’s wake word, the device will record everything it hears until the interaction has ended. It does this to optimize and personalize its performance specifically to the user. However, those recordings are stored indefinitely. In the Alexa app, you can choose to delete as many of these recordings as you’d like, or you can prevent use of your personal data entirely.
