As we all know, anything you say after the wake word "Alexa," is recorded, transmitted to Amazon, and stored on their massive servers. These recordings help Amazon learn from your voice.
But if you want to delete all of the stored recordings, you can easily do so by following these steps.
1. Go to
http://www.amazon.com/myx 2. Login with your Amazon account.
3. Click the "Your Devices" tab.
4. Your Echo(es) should be shown on the page. If you have more than one, click on the one that you want to delete the recordings from.
5. Click the "Manage voice recordings" link.
6. Click the "Delete" button to confirm.
