"California Governor Gavin Newsom signed the ' [1]California Opt Me Out Act ', which will require web browsers to include an easy, universal way for users to opt out of data collection and sales," reports the blog [2] 9to5Mac :

> [The law] requires browsers to provide a clear, one-click mechanism for Californians to opt out of data sharing across websites. The bill reads: "A business shall not develop or maintain a browser that does not include functionality configurable by a consumer that enables the browser to send an opt-out preference signal to businesses with which the consumer interacts through the browser...." Californians will need patience, though, as the law doesn't take effect until January 1, 2027.

Americans in some states — including California, Texas, Colorado, New Jersey and Maryland — "have the option to make those opt-out demands automatic whenever they surf the web," [3]reports the Washington Post . "But they can only do so if they use small browsers that voluntarily offer that option, such as DuckDuckGo, Firefox and Brave. What's new in California's law is that all browsers must give people the same option."

> That means soon in California, just using Google's Chrome, Apple's Safari and Microsoft's Edge can command companies not to sell your data or pass it along for ad targeting... It's an imperfect but potent and simple way to flex privacy rights — and becomes even more powerful with another simple privacy measure in California. Starting on January 1, California residents can fill out an online form once to completely and repeatedly wipe their data from hundreds of data brokers that package your personal information for sale.

But their article also suggests other ways readers can "try a one-click privacy option now."

"[S]ome national companies respect one-click privacy opt-out requests from everyone... This happens automatically if you use DuckDuckGo and Brave. You need to [4]change a setting with Firefox ."

"Download [5]Privacy Badger : The software from the Electronic Frontier Foundation, a consumer privacy advocacy group, works in the background to order websites not to sell information they're collecting about you."

"Use [6]Permission Slip from Consumer Reports . Give the app basic information, and it will help you do much of the legwork to tell companies not to sell your information or to delete it, if you have the right to do so."
