However, I do appreciate it if you accept some cookies and sessions, as they allow me to actually hide this notification. I might "require" it for other things that are specific to just this site, but I will guarantee that if you do accept these cookies that I will not use any data that I might be able to collect, mostly because I don't know how to collect this data, and I really have no use for it.
Also I need to set up a session so that this notification doesn't appear again in the next thirty days or so. This isn't to pressure you into using cookies, it's just that cookies are the only way to reliably remember that you don't want to see this notifications bar again, though I've tested this site for mobile use, and the bar isn't really that annoying.
If you really want to hide the bar, though, you can always just dismiss it. It will use localStorage to not display it the next time the page reloads. This should last until you decide to clear your browser data.
Regardless of what you choose, if you accept any cookies and / or data, they will expire thirty days after you last logged in.
So, in short:
