So you would suggest DNT would following the finality principle for the frequency capping. This has actually not only one implication but two. You indicated only one in your previous email. The first implication, as you said, is that data is only kept as long as necessary for the purpose for which it was collected. But the second implication is as important: collect only the data that is absolutely needed for the intended purpose. And I think some of the researchers here debate whether all the collection is really needed for frequency capping. Why is it so important to have the capping during the entire add campaign? Ninja said "per session" as users don't remember after one or two days anyway. Best, Rigo
