Virtual assistants such as Amazon's Echo break US child privacy law, experts say

Storing voice recordings of people younger than 13 via Alexa, Google Home and Siri appears to flout the Children's Online Privacy Protection Act

In a promotional video for Amazon's Echo virtual assistant device, a young girl no older than 12 asks excitedly: "Is it for me?". The voice-controlled speaker can search the web for information, answer questions and even tell kids' jokes. "It's for everyone," enthuses her on-screen dad.

Except that it isn't. An investigation by the Guardian has found that despite Amazon marketing the Echo to families with young children, the device is likely to contravene the US Children's Online Privacy Protection Act (COPPA), set up to regulate the collection and use of personal information from anyone younger than 13.
