              Greywall runs entirely on your machine. It does not phone home, collect telemetry,
              or transmit any data. No analytics, no crash reports, no usage tracking. The source
              code is open and auditable

              The Greywall landing page is a static site hosted on Vercel. We do not use cookies,
              analytics scripts, or tracking pixels. Vercel may collect minimal server logs
              (IP address, user agent, timestamp) as part of standard web hosting.

              When you use Greyscan at <a href="/greyscan" className="text-primary hover:text-primary/80 transition-colors">/greyscan</a>,
              the following happens:
            </p>
            <ul className="list-disc pl-6 space-y-2">
              <li>
                Your browser fetches the public file tree, dependency list, and README from GitHub&apos;s
                API directly. This data never passes through our servers during collection.
              </li>
              <li>
                To generate the threat report, a summary of the repo structure (file names,
                detected stack, dependency names, and up to 8,000 characters of the README) is
                sent to our server and forwarded to a third-party LLM provider for analysis.
              </li>
              <li>
                Results are cached in server memory for up to 24 hours to avoid redundant
                LLM calls for the same repository, then discarded. We do not persist scan
                results to disk or a database.
              </li>
              <li>
                No repository source code is read or transmitted. Only file paths, dependency
                names, and the public README are included.
              </li>
            </ul>
