Yo peeps, I’m currently looking into TCF Vendors, Ad partners and their whole corporate greed hellhole of tracking. I am writing a paper on this, and would like for everything to be factually correct. However, I am struggling to understand one particular part of this “transparency framework” and hope someone can help me clarify on cookie-duration.

As seen in the first thumbnail, the cookie duration is listed as 180 days. However, upon selecting > Storage Details, each cookie is displayed in further detail. In this detailed section, there are additional cookies with duration as high as 1825 days, not 180… So which is it? Currently, I’m (obviously) assuming the worst, as in, it being 1825 and not 180 days. There are additional cookies on this list, see spoiler below, that have cookies with the duration of 180 days. Why are the cookies with the highest duration listed on the first page? And if the answer is that “it would look worse”, then they also have cookies with lower amount of days than 180 that could have been used. There are multiple cookies with different durations, do all of them count?

If needed here is a spolier that includes all the cookies in detail from the Exactag GmbH vendor.

    while I am by no means an expert on this, my gut tells me that this is probably something to do with “nessecary” cookies vs advertising & tracking cookies. its a common loophole for other policies so I wouldnt be surprised if they had some way of circumventing the normal limitations for tracking because of “fraud protection” or the likes.

    looking at the cookie descriptors, all of the 1825 day cookies are used to “store &/or access information on device refreshes”. the shorter cookies are the only ones that also mention “measuring advertising & content performance”.

      Made the spoiler data/cookies more readable now.

      Thanks for your input, but not sure what you meant with your last sentence, could you clarify?

        thank you 🙏

        I meant that if you look at the “purpose” section of each cookie the ones that are older than 180 days are the only ones that dont mention advertising. thinking they may be related to the “nessecary” or “required” cookies that some websites have. I would presume they have their own or altered version of the other cookies policies since they have different purposes.

        apologies, I worded that poorly before.

          Ah I see now. I do think this will vary a lot from vendor to vendor and cookie to cookie though. The one I included was only a random one out of 198 different ones. Other cookies I’ve read through will have ad-measurements and tracking for 3000+ days too :<
