Privacy heads up for Chrome browser users

It does not track your history.

Basically, it puts a container (called cohort) in your browser and assigns it a number when you visit a website. Say for planetnexus.net it sets 1122 in the container and it associates that with the content on the page(s) visited. Next time you visit a site your browser itself defines the content of 1122.

Current approaches for ad selection rely on techniques such as tracking cookies and device fingerprinting, which are used by third parties such as advertisers to track individual browsing behavior.

With FLoC, the browser does not share its browsing history with the FLoC service or anyone else. The browser, on the user's device, works out which cohort it belongs to. The user's browsing history never leaves the device.

You can see a demo, and if your browser is currently supporting FLoC, by visiting: https://floc.glitch.me/

For the record, I'm using Google Chrome version 89.x and it says:

This browser's FLoC cohort ID is... not supported by this browser

This browser's FLoC cohort version is... not supported by this browser

FLoC is actually not bad. It is an attempt to limit browser cookies and their sharing of your browser history.
