@jonny I won’t subject you to my lengthy argument about why effectively you have to do this because anything you store for any purpose has to be defensible in a complaint so it is safer for you to always just tell everyone you’re potentially tracking and you don’t have to deal with it. We already went through a claim last year by a guy saying completely client side anti Adblock on YouTube (literally just if Adblock then don’t show video) was violating his privacy in the EU and he got them to agree.
