What the application collects
The public application does not create an account, profile, analytics identifier, advertising identifier, or server-side record of completed scenarios. It does not request location, camera, microphone, contacts, device fingerprint, gaze, pose, room map, or payment data.
Browser-local progress
When you explicitly mark a scenario complete, the browser may store only the scenario ID and completion state under killwebs:learning:v1. The record remains on the device, is not transmitted to the site, and can be cleared from any page footer.
Server logs
The hosting provider may create ordinary security and access logs, such as time, requested path, response status, user agent, and network address. KillWebs.com does not require application-level behavioral telemetry. Production operators should minimize retention, restrict access, and avoid logging full sensitive query strings.
External links
Links to KillChains.com, official source records, and author websites navigate only after user action. Those destinations operate under their own policies. The site does not embed their scripts, pixels, widgets, fonts, or APIs.
Your controls
Use “Clear local progress” in the footer to remove the optional learning-state record. Browser settings can also clear site data and service-worker caches.
