Recent research commissioned by the Campaign for a Commercial-Free Childhood and the Center for Digital Democracy allege that the Echo Dot Kids Edition's privacy practices violate the  Children’s Online Privacy Protection Act (COPPA), a federal law protecting the personal information of people under 13. The industry groups lodged the complaint with the Federal Trade Commission (FTC) arguing that amongst other things, Amazon fails to obtain proper parental consent to use children's data.
