Amazon knows that you care how information about you is used, and we appreciate your trust that we will do so carefully and sensibly. Here are answers to common privacy questions about Alexa and Echo devices.
No. By default, Echo devices are designed to detect only your chosen wake word (Alexa, Amazon, Computer, or Echo). The device detects the wake word by identifying acoustic patterns that match the wake word. No audio is stored or sent to the cloud unless the device detects the wake word (or Alexa is activated by pressing a button). With Alexa Guard, you can also configure supported Echo devices to detect specific sounds, such as the sound of smoke alarms, carbon monoxide alarms, and glass breaking.
When you speak to Alexa, a recording of what you asked Alexa is sent to Amazon's cloud, where we process your request and other information to respond to you. For example, when you ask, "Alexa, play top hits from Amazon Music," we use the recording of your request and information from Amazon Music to play top hits.
Any time audio is sent to the cloud, a visual indicator appears on your Echo device. For instance, the light ring on Amazon Echo will turn blue or a blue bar will appear on Echo Show. You can also configure certain Echo devices to play a short audible tone any time audio is sent to the cloud.
Yes. Our Echo devices are equipped with a microphone off button. When the button is pressed, the power to the microphones is disconnected and a dedicated red light is illuminated. When the microphones are turned off, your device cannot stream audio to the cloud, even when you say your chosen wake word.
Yes. You can review voice recordings associated with your account and delete those voice recordings one by one, by date range, by Alexa-enabled device, or all at once by visiting Settings > Alexa Privacy in the Alexa app or at http://www.delestrac.com/alexaprivacysettings. From either page, you can also choose to have your voice recordings older than 3 or 18 months deleted automatically. And you can delete all the voice recordings associated with your account all at once for each of your Alexa-enabled devices and apps by visiting Manage Your Content and Devices.
You can also enable the ability to delete your recordings by voice. Once enabled, you can delete the voice recording of your last request by saying “Alexa, delete what I just said” or you can delete all the voice recordings from your account for the day by saying "Alexa, delete everything I said today." Deleting voice recordings may degrade your Alexa experience. To enable deletion by voice go to Settings > Alexa Privacy > Review Voice History in the Alexa app or http://www.delestrac.com/alexaprivacysettings. When enabled, anyone with access to your Alexa-enabled devices can ask Alexa to delete voice recordings from your account.
Deleting voice recordings may degrade your Alexa experience. If you have changed your default marketplace while using an Alexa-enabled product, you will need to perform this step for each marketplace to delete all voice recordings associated with your account.
Alexa is designed to get smarter every day. For example, we use your requests to Alexa to train our speech recognition and natural language understanding systems using machine learning. Training Alexa with real world requests from a diverse range of customers is necessary for Alexa to respond properly to the variation in our customers’ speech patterns, dialects, accents, and vocabulary and the acoustic environments where customers use Alexa. This training relies in part on supervised machine learning, an industry-standard practice where humans review an extremely small sample of requests to help Alexa understand the correct interpretation of a request and provide the appropriate response in the future. For example, a human reviewing a customer’s request for the weather in Austin can identify that Alexa misinterpreted it as a request for the weather in Boston. Our supervised learning process includes multiple safeguards to protect customer privacy. You can manage the use of your voice recordings to improve our services and develop new features by visiting Settings > Alexa Privacy > Manage Your Alexa Data in the Alexa app.
