Am I FLoCed? A New Site to Test Google's Invasive Experiment | Electronic Frontier Foundation

Today we’re launching Am I FLoCed, a new site that will tell you whether your Chrome browser has been turned into a guinea pig for Federated Learning of Cohorts or FLoC, Google’s latest targeted advertising experiment. If you are a subject, we will tell you how your browser is describing you to every website you visit. Am I FLoCed is one of an effort to bring to light the invasive practices of the adtech industry—Google included—with the hope we can create a better internet for all, where our privacy rights are respected regardless of how profitable they may be to tech companies.

FLoC is a terrible idea that should not be implemented. Google’s experimentation with FLoC is also deeply flawed. We hope that this site raises awareness about where the future of Chrome seems to be heading, and why it shouldn't.

FLoC takes most of your browsing history in Chrome, and analyzes it to assign you to a category or “cohort.” This identification is then sent to any website you visit that requests it, in essence telling them what kind of person Google thinks you are. For the time being, this ID changes every week, hence leaking new information about you as your browsing habits change. You can read a more detailed explanation here.
