A new law in California taking effect on January 1, 2020 will give Californians the right to see, delete and stop the sale of the personal information that companies have compiled about them. The California Consumer Privacy Act applies to businesses operating in California that collect personal information for commercial purposes and meet certain condition – such as collecting the data of more than 50,000 people. This covers scores of tech companies, app developers, websites, mobile service providers, streaming TV services and even includes brick and mortar retailers like drug stores and other small businesses. The effort could have national implications as well – some companies including Microsoft have said they will honor the data rights in the California law for consumers nationwide.
