The California Consumer Privacy Act (CCPA) is a California state law passed in 2018 that outlines rights for California residents related to their personal data, and how it may legally be used by businesses. CCPA grants Californians with the right to access, delete, and opt out of the sale of their personal data to third parties. It also requires businesses to clearly communicate their data collection and usage practices, and to employ reasonable measures to secure any personal data they collect. CCPA went into effect Jan 1, 2020.
