Many consumers wonder how much of their data is being collected by Alexa — and for what purpose.

In February we explored the topic “Alexa, are you spying on me?” If you remember that segment, then you remember the answer was, “I only send audio back to Amazon when you activate me. For more information, view Amazon’s privacy notice.”

In doing more research, there is a way to hear and then delete everything your device has recorded. But first, let’s see why Amazon is recording us.

When asked if humans are listening in to recordings and conversations picked up by Alexa, Amazon, in its lists of frequently asked questions, states: “We use your requests to Alexa to train our speech recognition and natural language understanding systems.”

That’s followed by the claim that they take the security and privacy of customers’ personal information seriously. It goes on to state that they only annotate an extremely small sample of Alexa voice recordings in order to improve the customer experience. It all sounds innocuous if you don’t think about it too hard.

But what are they listening to? If you want to know exactly what Alexa has been recording in your home, go to your Alexa app and click on Settings. Then select Alexa Account, next select Alexa Privacy and finally select Review Voice History. From there you can use the pulldown menu to select the date range you want to review.

You can delete a date range or your entire history. To delete all you might have to visit “Manage Your Content and Devices” page at Amazon.com then click on the Devices tab, selecting an Alexa-enabled product and clicking Device Actions to find the Delete All Recordings option. Another option is to contact Amazon customer service and have them delete your recordings.

What does Amazon say about you exercising your right to delete your voice recordings? They say, “This could degrade your Alexa experience.” Bottom line: It’s up to you to protect your privacy.
