No, you dont! Only if you use third party services to do that or collect data thats not essential to your business. Its just coloquially called a "Cookie Banner", but the laws DONT require you to put up one as soon as you set one cookie!

It does if the cookie contains any uuid that might be linkable to a user's identity (which is obviously necessary if you want to perform rudimentary self-hosted analytics on unique user visits)

Only if it is a “tracking cookie”, and lasts for more than one day. But how do they define these terms ??
