The whole policy: nothing you do on Country Warrior leaves your browser. Your theme choice and settings are kept in this browser's local storage, on your machine. There are no analytics, no cookies, no accounts, and no third-party requests of any kind.
There is nothing clever behind that. The site is a pile of static pages; the only thing it ever remembers about you is which colour theme you picked, and it remembers that on your machine, where you can delete it by clearing your browser's storage. No consent banner appears because there is nothing to consent to.
If that ever changes, this page will say so first, in plain language.
