CalOPPA, or the California Online Privacy Protection Act, was the first state law in the U.S. to require a publicly-accessible Privacy Policy for any commercial website that collects personal information from California residents.

CalOPPA has specific requirements for what information a Privacy Policy must contain, including the categories of personal information collected, the categories of third parties the information may be shared with, and what rights users have to review or change their personal information held by the business.
