Cookie Policy and local storage

Version 2026-09-29

Katanith only uses strictly necessary technical storage so the site works. We do not use analytics, advertising or tracking cookies, so we show no consent banner. If we ever add them, we will ask your permission first.

2. Legal basis

All of the above is technical and necessary to provide the service you request, or a preference you choose (language, theme), so it is exempt from consent under art. 22.2 of the Spanish LSSI and e-privacy rules. Turnstile relies on our legitimate interest in protecting the service.

3. Payments and Google sign-in

When you pay, Stripe takes you to its own page (stripe.com), which applies its own cookie policy. If you choose “Continue with Google”, Google applies its own on its sign-in page.

4. How to delete them

You can delete local storage and cookies in your browser settings. If you clear session storage you will need to sign in again.
