In a little over three months, California will see the widest-sweeping state-wide changes to its privacy law in years. California’s Consumer Privacy Act (CCPA) kicks in on January 1 and rolls out sweeping new privacy benefits to the state’s 40 million residents — and every tech company in Silicon Valley.

California’s law is similar to Europe’s GDPR. It grants state consumers a right to know what information companies have on them, a right to have that information deleted and the right to opt-out of the sale of that information.
