About HeimWall

Signal, not surveillance. See how your engineers use Cursor, Claude Code, and Copilot: catch leaked secrets, PII, and confidential data, without blocking them or reading their prompts. Nothing sits in your send path, your prompt reaches the tool untouched, and what you type into an AI tool is never sent to us. To read your prompt before it is sent, the app reads the composer through the macOS Accessibility API and watches the clipboard. Accessibility is a wide permission and macOS does not offer a narrower one for this.

About react-stereogram demo

Image URLs work with images served from your own project, but a remote image whose server doesn't send an Access-Control-Allow-Origin (CORS) header can't have its pixels read back from the canvas, so the render fails. To keep the demo predictable we force upload for now, the file is read entirely in your browser's memory and is never sent anywhere. For images, brighter pixels come nearer, if your subject is darker than its background (most photos and logos), tick invert depth so the subject pops instead of the background.
