Last month, we reported Meta and Mozilla moved forward with live testing of their Interoperable Private Attribution (IPA) design. The unlikely duo declared intent to prototype in Chrome, even as Chrome moves forward with its Attribution Reporting API (ARA) and Private Aggregation API (PAA).

PATCG met in person for two days in New York City. Coir was there. As predicted in our January brief, the focus of the meeting was to resolve objections to the working group charter and achieve closer alignment on an eventual attribution standard.

This brief is the first of its kind. A lot is happening in privacy-related W3C meetings, Github issues and side conversations. We follow all we can. We pull meaningful overall highlights and summaries by focus area, plus share thoughts on how your business might respond.
