Flamenco Warrior has no accounts, no analytics, no cookies and no third-party requests. It is a set of static pages, and the only things it remembers are the ones that make it easier to use: the colour theme you picked, and the last root note you were looking at in a chord or scale section. Both are kept in this browser's local storage, on your own device, and clearing your browser's storage deletes them.
Because nothing is collected, there is nothing to consent to, and no banner stands between you and the page.
If that ever changes, this page will say so first, in plain language.
