The Children's Online Privacy Protection Act of 1998 (COPPA) is a United States federal law. The act, effective April 21, 2000, applies to the online collection of personal information by persons or entities under U.S. jurisdiction about children under 13 years of age, including children outside the U.S. if the website or service is U.S.-based. It details what a website operator must include in a privacy policy, when and how to seek verifiable consent from a parent or guardian, and what responsibilities an operator has to protect children's privacy and safety online, including restrictions on the marketing of those under 13. - Source: Wikipedia
