In the context of the web, what is a "functional cookie"?
Correct: "helps personalise the website's services for you." In the study, only 16% of participants picked it — most chose "needed for the website to work," which is actually the definition of a strictly necessary cookie. Even "performance" cookies were understood by under half (47.6%). The labels people are asked to consent to are largely meaningless to them.
