Even google-chrome doesn't require you to do any KYC or that sort of thing to use the browser.
They don't need to. If you use Chrome, then Alphabet Inc. already have a complete log of everything you do online, every site you visit, every purchase you make, every communication you make. KYC is irrelevant to them when they know it all already.
You can always configure your cookie settings and make sure your data is protected.
You are completely fooling yourself if you think that changing settings from within Chrome will stop Chrome from spying on you and logging your data. The same is true for all Google products. Even when you explicitly tell Chrome or Google to stop spying on you, they keep doing it. All that changes is you don't get to see the "history" that they have stored on you anymore.
