Why so far away?
We don’t want to keep pestering you with that warning in the bottom of the screen, so we make it expire way out into the future so you can browse freely.
What about if there are changes?
If there are any changes we would like to alert you about, we will expire the cookie straight away once you come back to the site, if we have made any important changes to the way our cookies work. Usually, we would ask for consent before creating a new cookie.
