The "clicktracking-session" cookie on the en-wiki remains the same before (anonymous), during (logged in), and after logout. This allows the tracking of a user after logout until they have cleared their cookies. It also allows the correlation of logins from "different" users in the same browser session. The clicktracking-cookie should also be listed in privacy policy: https://wikimediafoundation.org/wiki/Privacy_policy For how long is clicktracking data kept and what is its purpose (wikipedia doesn't have advertising...so for whom are the analytics)?

Diederik, could you look into this one?
Any progress? It's not hard to fix...just delete the cookie on logout along with the other cookies.
Fixed in Gerrit change #21554.
