Cookie Policy

What we store on your device, and how to clear it.

Last updated: 9 November 2026.

What we mean

"Cookies" here also covers similar technologies such as local storage. Neon Knuckles itself uses only essential storage, and our own promotions set no third-party cookies. If we switch on Google AdSense, Google sets cookies of its own, and its consent message asks for your choice before it sets any that need consent. We do not use analytics cookies. We count page views and campaign sources on our own server without setting or reading any cookie or local storage item (see the privacy policy), so there is nothing of that kind to switch off here.

Essential (always on)

These are needed for the game to remember your choices and do not track you across sites.

Advertising cookies and storage

Our own promotions are stored and counted in your browser only (see the last row of the table). Google AdSense cookies apply only when Google ads are shown; we may switch these on, and until we do none of the Google rows below are in use. When they are on, Google and its advertising partners may set cookies or use similar identifiers on your device. They are set by Google, not by us, and they can change, so we cannot list every one here. They are used to deliver and measure ads, limit how often you see the same ad, prevent fraud and, if you agree, to personalise ads. Google describes them at policies.google.com/technologies/cookies.

Nothing leaves your browserNo, essential

Personalised and non-personalised ads. This applies only when Google ads are shown. If you accept personalised ads, Google may use your cookies and identifiers to show ads based on your interests. If you refuse, you may still see ads, but they are non-personalised or limited: based on the page and your rough location, not your history. Either way, no ads are shown during a fight; short break cards can appear between fights.

Changing your mind

When Google ads are on, use the Privacy choices link at the bottom of any page to reopen Google's consent message and change your answer at any time. You can also delete cookies and local storage in your browser settings (clear site data for neonknuckles.com); the game then starts with its defaults and, if Google ads are on, Google asks again. Google ad settings are at adssettings.google.com. For how we handle personal data, see the privacy policy.
