Game data

Every game and every AI model runs entirely inside your browser. Your play, scores, and inputs are never sent to our servers (except the online-match connection and the optional leaderboard submission — see below).

Leaderboards & ghosts

Some games have a daily-course leaderboard. When you finish a run on “Today's Course”, your score, that run's input recording (the control stream used to replay it), a randomly generated anonymous device ID, and your optional nickname are sent to and stored on our server (Cloudflare). Your nickname and score appear publicly on the leaderboard, and the input recording is served as a public “ghost” other players can race against. Nothing else is sent; no account or personal details are required. Nicknames are public — please avoid using your real name. Your IP address is processed transiently for rate limiting (abuse prevention) and is not stored. Free-mode play sends nothing. Contact us below if you want an entry removed.

Online play

Online matches in Neural Corridor normally run as direct peer-to-peer (P2P) connections between players. To establish the connection, a public STUN service (Google, a third party) and our own server (Cloudflare, for the handshake only) handle your network address (IP); gameplay traffic does not transit them when a direct connection succeeds. When a direct connection cannot be established, the match may be relayed through our own server — only then does gameplay traffic transit it, and its contents are never exposed to third parties. In either case, your IP address is shared with your opponent as part of establishing the connection. Share connection codes and links only with people you trust.

Advertising

This site plans to serve ads through Google AdSense. Once ads are live, Google and its partners may use cookies (including the DoubleClick DART cookie) to serve and optimize ads based on your visits to this and other sites. You can opt out of personalized advertising at Ads Settings. See Google's policies and terms for details.

Cookies & consent

The cookies this site uses are as follows (once ads are live). Advertising cookies: personalized-ad cookies served by Google LLC (including the DoubleClick DART cookie; retained up to 13 months). Analytics: Cloudflare Inc. Web Analytics (a cookieless method, but this site loads it only after consent). A consent banner appears on your first visit. Analytics scripts load only after you consent. Advertising scripts do not load until ads go live. The only first-party cookie we set is a functional `lang` cookie that remembers your language choice (EN/JA) — it does not require consent.

Analytics

This site uses Cloudflare Web Analytics. It is cookieless: it collects anonymous statistics such as page views, approximate region, and referrer. It does not use cookies and does not identify individuals. Your gameplay, scores, and inputs are not sent to Cloudflare Web Analytics.
