The California Consumer Privacy Act (CCPA) is a privacy law that was enacted in the state of California in June 2018 and became effective on January 1, 2020. The CCPA gives California residents the right to know what personal information is being collected about them, the right to request that their personal information be deleted, the right to opt-out of the sale of their personal information, and the right to access their personal information.

The CCPA applies to companies that do business in California and that meet certain thresholds for revenue or data collection. The law requires covered businesses to provide certain disclosures about their data collection practices and to comply with requests from California residents to access, delete, or opt-out of the sale of their personal information. The CCPA also includes a private right of action that allows California residents to sue businesses that violate the law.

The CCPA is often considered one of the most comprehensive data privacy laws in the United States, and it has been influential in shaping other privacy laws at both the state and federal level.
