California’s big consumer privacy law goes into effect on Jan. 1. It’s the first law in the U.S. that demands that companies give consumers more control over their information and more power over what they can do with that information once they have it. On the consumer side, you can now ask companies to show you everything they have on you for free up to twice a year. You can ask companies to delete the data, and the law requires companies to give you an easy way to opt out of having your personal information sold. Jessica Lee, a partner at the law firm Loeb & Loeb and co-chair of the privacy, security and data innovations practice there, helps us understand the new law.
