European Union laws require you to give European Union visitors information about cookies used and data collected on your blog. In many cases, these laws also require you to obtain consent.
Out of courtesy, we have added a notice on your blog to explain Google's use of certain Blogger and Google cookies, including use of Google Analytics and AdSense cookies, and other data collected by Google.
You are responsible for confirming that this notice actually works for your blog, and that it displays. If you employ other cookies, for example by adding third-party features, this notice may not work for you. If you include functionality from other providers there may be extra information collected from your users.Which is... fine, I guess? The weird part is that I have no idea what the notice says, because I'm in Canada, and the notice doesn't appear for Canadian users. Hopefully the thing is actually working, since I have no way to know; blogger's relevent help page says that it should be active automatically, with no action needed from me, which I find to be somewhat at odds with the notice itself, which says that I'm somehow supposed to be responsible for ensuring that it's working, even though I apparently can't do that from here.
If Blogger's default GDPR notice says anything you object to, please direct those objections to Google, who are entirely responsible for the no-doubt-legalese passages in question. If it's not there at all, please feel free to leave a comment on this blog post or something to let me know.
For the record, I have my browser options set to delete all cookies automatically when Firefox closes (and, yes, I use Firefox - it's what I'm used to, and Quantum's performance is close enough to Chrome's to be acceptable), and to accept third-party cookies only from sites I've already visited. Since Firefox is also set to clear my history when it closes, and since I also run two ad-blockers (uBlock Origin and AdBlocker Ultimate), I feel pretty okay with the level of data that people can collect about me without my knowledge. I'm probably not doing much to slow the the likes of Facebook with their shadow profiles, but I shouldn't be broadcasting much of anything to the world that I'd rather keep quiet.
Remember... it's not paranoia if they are watching you. And they definitely are watching you. C'est la vie.
