    <article class="prose">
      <h2 id="no-accounts">1. No User Accounts or Personal Profiles</h2>
      <p>
        <strong>FB4KDownloader.com</strong> operates as an anonymous, open web utility. We do not require account registration, usernames, passwords, phone numbers, or credit card details. When you visit our site, you remain completely anonymous to us.
      </p>

      <h2 id="stream-handling">2. How Our Server Handles Video Streams</h2>
      <p>
        To be completely transparent about our real server architecture:
      </p>
      <ul>
        <li><strong>Zero Permanent Video Storage:</strong> When you request a download, our server fetches public stream chunks from Facebook's Content Delivery Network (CDN) and immediately pipes them in real-time to your client browser through an active HTTP socket.</li>
        <li><strong>No File Caching on Disk:</strong> Videos are never saved to our server hard drives or retained in permanent databases. As soon as the transfer finishes or is cancelled, volatile RAM buffers are instantly freed.</li>
        <li><strong>No URL History Dossiers:</strong> We do not associate the Facebook URLs you paste with your identity or build behavioral tracking profiles.</li>
      </ul>

      <h2 id="server-logs">3. Server Logs &amp; Rate Limiting (Security)</h2>
      <p>
        Like any web application operating on the public internet, our web server processes standard network metadata for operational security:
      </p>
      <ul>
        <li><strong>Rate Limiting:</strong> Our backend implements rate limiting (capped at 150 requests per 15-minute window per IP) to protect our infrastructure from automated denial-of-service (DDoS) flooding. IP addresses are evaluated in volatile memory by the rate-limiter middleware.</li>
        <li><strong>Rolling Debug Log:</strong> To detect connectivity bugs with upstream CDNs, our server maintains a temporary in-memory rolling buffer of the last 50 error events. These logs are stored strictly in RAM and are overwritten continuously.</li>
        <li><strong>Headers Collected:</strong> Standard HTTP request headers (browser User-Agent, language, and referrer) are sent by your browser to ensure responsive layout rendering.</li>
      </ul>

      <h2 id="cookies-ads">4. Cookies &amp; Third-Party Advertisements</h2>
      <p>
        We do not use tracking or profiling cookies of our own. However, our website utilizes standard third-party services:
      </p>
      <ul>
        <li><strong>Preferences Cookie / LocalStorage:</strong> We store a simple local key (<code>fb4k_cookie_consent</code>) in your browser's LocalStorage to remember when you have acknowledged our cookie notice so we don't display it repeatedly.</li>
        <li><strong>Advertising Partners:</strong> To cover bandwidth and server hosting costs, we display non-intrusive advertisements from verified monetization networks. These partners may place standard cookies to measure ad impressions and prevent click fraud in accordance with their respective privacy policies.</li>
      </ul>

      <h2 id="contact-dpo">5. Data Privacy Inquiries</h2>
