Google is running a Chrome “origin trial” to test out an
experimental new tracking feature called Federated Learning of
Cohorts (aka “FLoC”). According to
the trial currently affects 0.5% of users in selected regions,
including Australia, Brazil, Canada, India, Indonesia, Japan,
Mexico, New Zealand, the Philippines, and the United States. This
page will try to detect whether you’ve been made a guinea pig in
Google’s ad-tech experiment.
