Cookies are not essential for operating a website. This is something that many people are unaware of. Among other things, cookies are used to store user data. For example, when you add something to your shopping cart on Amazon, this information is stored in a cookie and, depending on your settings, is saved for the current session or for a longer period of time. When you return to the site, the product is still in your shopping cart and you can continue shopping. Sounds convenient and harmless, right?
But what if this data is used to track people's surfing behavior? This personal data can be aggregated and made available to third parties. Google and Co. do the same thing, and that is no longer allowed, at least not without the user's consent. And we're not talking about a small notice hidden somewhere on the website, but about actively confirming these cookies when entering the site.
