        <h2>Summary</h2>
        <p>
          Your Markdown documents stay on your device. We don't upload them, we don't read them, and
          we don't use them to train anything. This page explains the details.
        </p>
        <h2>What we collect</h2>
        <ul>
          <li>
            <strong>Drafts you write.</strong> Saved to your browser's local storage. Never sent to
            our servers.
          </li>
          <li>
            <strong>Theme and editor preferences.</strong> Also stored locally so the app remembers
            your settings.
          </li>
          <li>
            <strong>Anonymous request logs.</strong> Our hosting provider records standard web
            request metadata (timestamp, IP address, user agent) for abuse prevention and
            performance monitoring.
          </li>
        </ul>
        <h2>What we don't collect</h2>
        <ul>
          <li>The content of your Markdown documents</li>
          <li>Personally identifying information beyond what's in standard server logs</li>
          <li>Behavioral analytics or cross-site tracking</li>
        </ul>
        <h2>Cookies</h2>
        <p>
          {siteConfig.name} does not set tracking cookies. The site stores your theme preference and
          drafts in your browser's local storage, which is functionally similar but is not shared
          with our servers.
        </p>
        <h2>Third parties</h2>
        <p>
          We use the following third-party services, all of which we've audited for privacy:
        </p>
        <ul>
          <li>
            <strong>Vercel</strong> — hosting and edge content delivery.
          </li>
          <li>
            <strong>Google Fonts</strong> — served statically and self-hosted via Next.js Font.
          </li>
        </ul>
        <h2>Your rights</h2>
        <p>
          Because we don't collect personal data, there's nothing for us to delete on request. You
          can clear your local data at any time from your browser's site settings.
        </p>
