HIQaH! QaH! TAG!

I'm requesting a TAG review of the FLoC API.

In today's web, people’s interests are typically inferred based on observing what sites or pages they visit, which relies on tracking techniques like third-party cookies or less-transparent mechanisms like device fingerprinting. User privacy could be better protected if interest-based advertising could be accomplished without needing to collect a particular individual’s exact browsing history.

The FLoC API would enable ad-targeting based on the user’s general browsing interest, without the websites knowing their exact browsing history.

Please read the Security and Privacy self-review for the privacy goals and concerns.
