Seed stored in session cookie, do I need cookie banner?

Hello Kirby Forum!

So I’m storing the seed from a random function in kirbys session cookie, a part from that nothing else is stored there by me.

From my understanding of the GDPR law you only need to have a cookie banner when you store personal information in the cookie. I’ve checked the sessions stored on the server and I can see that Kirby also stores some other information in it, is that info GDPR compliant? If it isn’t is there away to make it GDPR compliant? I really don’t like adding the cookkie banner haha.

A session from the site looks like this.
