COPPA, or the Children's Online Privacy Protection Act, is a U.S. federal law aimed at protecting the online privacy of children under the age of 13 years old. The act applies to any commercial website or online service that is targeted to children. It requires a Privacy Policy and that parental consent is obtained before personal information is collected from children under 13. Parents have rights to request what information is held about their children and to revoke consent at any time.
