I have been trying to work how the WMF or its suppliers have chosen to use pixel tracking methods on Wikimedia projects, and exactly what data is tracked, who can access it and if it ever gets officially deleted, but failed so far.
There was some past speculation that some banners were using pixel tracking, but apart from the cookie statement published by request of WMF legal in 2015,[1] I have been unable to find precise explanations of how this has been part of banner design, used on external landing pages, or whether pixel tracking had ever been used more directly by being integrated or tested on Wikimedia projects. Naturally this leads to questions about legitimate use of pixel tracking data and what/who it is tracking.
It would be much appreciated if anyone can provide a link to an official statement given by the WMF that pixel tracking is used on its sites outside of fundraising banners, or its supplier's sites, and any example cases or reports of where it is happening.
