In an e-mailed statement, Echometrx denied the allegations. "Echometrix does not collect personally identifiable information or expose the source of any digital content," the statement said. "The company has never and will never collect, distribute or sell personal information as defined by COPPA."

Kimberly Nguyen, a lawyer for EPIC, said the group's main concern is with the collection of personal data on children. "According to COPPA, companies can't collect personal data from children" without parental consent, which is precisely what Echometrix is doing, Nguyen claimed. "They are violating federal statutes," by their actions, in addition to FTC rules relating to the disclosure of privacy policies, Nguyen said.

The FTC has not responded to EPIC's complaint against Echometrix.
