if you don't track users you don't need GDPR consent dialogs

I think in the past you still needed some info box in the corner with a link to the data policy. But I think that isn't needed anymore (to be clear not a consent dialog, a informational only thing). Also you can without additional consent store a same site/domain cookie remembering you dismissing or clicking on it and not showing it again (btw. same for opting out of being tracked).

But there are some old pre-GDPR laws in some countries (not EU wide AFIK) which do require actual cookie banners (in difference to GDPR consent dialogs or informational things). EU want them removed, but politic moves slow AF so not sure what the sate of this is.

So yes without checking if all the older misguided laws have been dismissed, you probably should have a small banner at the bottom telling people "we don't track you but for ... reasons .. [link] [ok]" even if you don't track people :(. But also if they haven't gotten dismissed they should be dismissed very soon.

Still such a banner is non obnoxious, little annoying (on PC, Tablet, a bit more annoying on Phone). And isn't that harass people to allow you to spy on them nonsense we have everywhere.
