1. Information stored in your browser
- Your racer name and most recently selected track are stored in local browser storage.
- The
kr_racer cookie is a random identifier used to distinguish personal best times submitted from the same browser. It is set by the server and cannot be read by JavaScript.
- In production, the
kr_browser and kr_challenge cookies support short browser verification and session checks intended to reduce automated abuse.
You can delete local storage and cookies through your browser's site-data settings. Removing them may reset your personal-record association and browser verification session.
2. Rankings, replay checks, and abuse prevention
When you submit a single-player result, K-Racing processes your racer name, track and track version, completion time, compressed control inputs sampled at fixed intervals, and the submission time. The server can replay these inputs to check the result.
To maintain service reliability and investigate abusive use, K-Racing may process an IP address, request time, response status, browser-session identifier, and limited security logs. A sanitized racer name, completion time, and achievement date are shown publicly on the ranking. The game does not collect payment details or precise location data.
3. Online races and WebRTC
Room codes, racer names, ready states, and connection-negotiation messages pass through the K-Racing signaling server. When possible, live driving data travels directly between a participant's browser and the host through WebRTC.
Depending on network conditions, your IP address may be visible to the connection peer. If a direct connection cannot be established, K-Racing's authenticated TURN server may relay the traffic.
4. Hosting, security, and Google advertising
Cloudflare may provide DNS, transport security, caching, and automated traffic protection. Cloudflare and the hosting provider may process IP addresses and request logs while delivering and protecting the service.
If H5 Games Ads is approved and advertising mode is enabled, Google AdSense and Google's advertising partners may process cookies, device information, IP addresses, and ad-interaction data for ad delivery, frequency control, measurement, fraud prevention, and personalization decisions. Where consent is required, including the EEA, United Kingdom, and Switzerland, choices are requested through Google's consent management platform. A refusal is passed with the advertising request.
K-Racing does not request ads during a race. The result is shown first, and an ad opportunity is requested through the official H5 Games Ad Placement API only when a player first uses a navigation action on the results screen. An ad may not appear because of inventory, consent, or frequency limits.

5. Retention, your choices, and contact
Ranking entries may be retained while needed to provide competition history and investigate invalid results. Security logs are retained only for operational and abuse-prevention needs, then removed through routine rotation. K-Racing is not designed for children under 13 and does not intentionally collect personal information from children under 13.
