Amazon is being accused of indefinitely storing conversations with sensitive information held between children and the company's kid-friendly Echo Dot Kids devices. A complaint to be filed with the FTC on Thursday alleges this is a violation of the Children’s Online Privacy and Protection Act. According to The Wall Street Journal, investigators were unable to change or delete addresses, phone numbers and other individual information stored by the Echo Dot Kids device without calling Amazon customer service. Speaking to The Journal, an Amazon spokesperson said the company follows federal privacy laws. Senator Edward Markey also urged the FTC to investigate these claims, adding, “Children are a uniquely vulnerable population. We urge the Commission to take all necessary steps to ensure their privacy."
