DarkMatter — Neon Tunnel uses a deep indigo and midnight violet palette evoking the void of deep space, dark matter fields, and quantum tunnelling phenomena. The game is a tunnel navigation game where players steer a photon through narrowing procedurally generated tunnels that scroll faster over time. It is provided entirely free of charge. Our privacy philosophy is as deliberate as our visual design: we collect no personal information whatsoever.
No data leaves your device. No server stores anything about you. No account is required.
At no point — during play, at session start, or at session end — do we collect, process, store, or transmit:
We use browser localStorage exclusively to save your personal best under the key dm_best. This:
We use no cookies, no sessionStorage, no IndexedDB, no service workers that store data, and no Web SQL.
This game is 100% free. There are no in-app purchases, no virtual currencies, no loot boxes, no gambling mechanics, and no prizes. Every score and achievement has zero monetary value.
DarkMatter generates tunnel wall segments procedurally in real time, with centre position and width varying incrementally between segments. All tunnel geometry, photon position, and collision state exist only in the browser tab's memory. No positional data, navigation paths, or session lengths are transmitted to any server.
DarkMatter uses touchstart/touchend and mousedown/mouseup events to detect left/right steering input. No continuous pointer tracking is performed — only the side of the screen tapped is registered. No pointer coordinates are stored or transmitted beyond what is needed for the immediate left/right direction decision within the current frame.
We load Orbitron and Rajdhani typefaces from Google Fonts CDN at fonts.googleapis.com. Google may log anonymised font-request metadata per their own Privacy Policy. No other third-party service is embedded in this game. You may block fonts.googleapis.com and fonts.gstatic.com in your browser — the game continues to function using system font fallbacks.
Our web hosting provider may retain minimal server access logs (HTTP response codes, timestamps, approximate region) for uptime monitoring and abuse prevention. These logs are not linked to individual users and are purged automatically on a rolling schedule.
Because we collect no personal data from anyone, there is no special data risk for younger players. We comply fully with the intent of COPPA (United States), GDPR Article 8 / GDPR-K (European Union), the UK Children's Code, PIPA, and equivalent children's privacy frameworks globally.
Under GDPR, CCPA, and similar laws, you have rights including access, correction, portability, and erasure. Since we store no personal data on our servers, these rights apply only to your browser's localStorage entry, which you may delete at any time independently. Contact us if you have questions.
If our privacy practices change materially, we will update this page and revise the effective date. Continued use of the game after any update constitutes acceptance of the revised policy.
