The California Consumer Privacy Act (CCPA) – a new slate of provisions related to how companies gather and utilize consumer data in the Golden State – will go into effect on January 1, 2020.

But to be compliant with this legislation – which has been compared to the European Union’s General Data Protection Regulation (GDPR) – businesses must begin tracking their personal data usage on January 1, 2019.

“That means on January 1, 2020, qualifying companies can be asked for certain pieces of information, but that information has to be for the preceding 12 months,” said David Reim, chief privacy officer at DMD, a digital marketing company that services the healthcare industry.

“So, on January 1, 2020, companies basically have to tell those [consumers] who ask [about] everything that happened in 2019.”

During a session at the 2018 Digital Pharma East conference in Philadelphia, Reim further emphasized this point: “The compliance date is the first – and the most important – thing to know about the new CCPA, which likely will affect almost all life science companies.”
