The Children's Online Privacy Protection Act (COPPA) is a U.S. law designed to protect the privacy of children under the age of 13. It requires websites and online services that collect personal information from children to obtain verifiable parental consent before doing so. This law aims to ensure that parents are aware of what information is being collected and how it is used. COPPA also mandates that websites must provide a clear privacy policy detailing their data collection practices. Additionally, it restricts the types of information that can be collected from children and gives parents the right to review and delete their child's personal data.
