# Browsing Privacy & Safety

<p>Comet includes built-in protections to make everyday browsing safer. This article explains how Comet blocks unwanted content, handles cookies, manages site permissions, and helps you understand connection security.</p>

<hr />

<h2 id="h_759e0d30e8"><b>Ad & Script Blocking</b></h2>

<p>Comet automatically blocks:</p>

<ul>
  <li>
    <p>Advertising scripts</p>
  </li>

  <li>
    <p>Fingerprinting attempts</p>
  </li>

  <li>
    <p>Unwanted third-party scripts</p>
  </li>
</ul>

<p>These protections help reduce profiling and prevent sites from following you across the web.<br />​</p>

<p>You can view monthly statistics on the <b>New Tab Page</b> in the <i>Comet protects you</i> widget.</p>

<hr />

<h2 id="h_62f74ef165"><b>Third-Party Cookies</b></h2>

<p>Third-party cookies are allowed by default for compatibility, but you can change this:</p>

<ul>
  <li>
    <p>Allow</p>
  </li>

  <li>
    <p>Block</p>
  </li>

  <li>
    <p>Block only in incognito</p>
  </li>

  <li>
    <p>Block cookies after closing sites</p>
  </li>
</ul>

<p>Configure this in:<br />​<b>Settings → Privacy and security → Third-party cookies</b></p>

<p>Blocking third-party cookies improves privacy but may break:</p>

<ul>
  <li>
    <p>Social logins</p>
  </li>

  <li>
    <p>Embedded widgets</p>
  </li>

  <li>
    <p>Some payment flows</p>
  </li>
</ul>

<hr />

<h2 id="h_8b32278919"><b>Clear Site Data</b></h2>

<p>Comet allows you to remove cookies, cache, and stored data for individual sites or all sites at once.</p>

<p>Where to manage it:</p>

<ul>
  <li>
    <p><b>comet://settings/content/all</b> (site data overview)</p>
  </li>

  <li>
    <p><b>Settings → Privacy and security → Delete browsing data</b></p>
  </li>
</ul>

<p>Clearing site data signs you out of most accounts and resets site preferences.</p>

<hr />

<h2 id="h_51a6af6018"><b>Site Permissions</b></h2>

<p>Each site can request access to features such as:</p>

<ul>
  <li>
    <p>Camera</p>
  </li>

  <li>
    <p>Microphone</p>
  </li>

  <li>
    <p>Location</p>
  </li>

  <li>
    <p>Notifications</p>
  </li>

  <li>
    <p>Clipboard</p>
  </li>

  <li>
    <p>File system access</p>
  </li>

  <li>
    <p>Pop-ups and redirects</p>
  </li>
</ul>

<p>Control these globally or per-site in:<br />​<b>Settings → Privacy and security → Site settings</b></p>

<p>Each permission can be set to:</p>

<ul>
  <li>
    <p><b>Allow</b></p>
  </li>

  <li>
    <p><b>Block</b></p>
  </li>

  <li>
    <p><b>Ask every time</b></p>
  </li>
</ul>

<p>Changes take effect immediately.</p>

<hr />

<h2 id="h_3dedbe3fd8"><b>Safe Browsing & Malware Defense</b></h2>

<p>Comet uses built-in protections to help detect:</p>

<ul>
  <li>
    <p>Known malicious websites</p>
  </li>

  <li>
    <p>Dangerous downloads</p>
  </li>

  <li>
    <p>Sites attempting phishing</p>
  </li>

  <li>
    <p>Malware-hosting domains</p>
  </li>
</ul>

<p>When a threat is detected, Comet warns you before the page loads.</p>

<p>These checks rely on frequently updated, privacy-preserving lists. Personal browsing content is not sent to external services.</p>

<hr />

<h2 id="h_39ffb163ea"><b>Password Manager & Autofill Security</b></h2>

<p>Comet autofill is designed to work only on verified domains.</p>

<ul>
  <li>
    <p>Autofill does not activate on suspicious or mismatched sites.</p>
  </li>

  <li>
    <p>Passwords are decrypted locally only after your OS verifies your identity (Touch ID, Face ID, Windows Hello).</p>
  </li>

  <li>
    <p>Comet cannot read or export passwords unless you explicitly choose to do so.</p>
  </li>
</ul>

<p>Manage settings in:<br />​<b>Settings → Autofill and passwords</b></p>

<hr />

<h2 id="h_202bd5ddef"><b>Incognito Mode Behavior (for browsing safety only)</b></h2>

<p>In Incognito mode:</p>

<ul>
  <li>
    <p>Comet does not save browsing history, cookies, or cache</p>
  </li>

  <li>
    <p>Third-party cookies remain blocked unless explicitly allowed</p>
  </li>

  <li>
    <p>Extensions are disabled unless manually enabled</p>
  </li>
</ul>

<p>Network-level tracking (e.g., by your ISP or employer) is still possible.</p>

<hr />

<h2 id="h_01b03feb33"><b>Keeping Comet Secure</b></h2>

<p>The easiest way to stay protected is to keep Comet up to date.<br />Updates include:</p>

<ul>
  <li>
    <p>Security patches</p>
  </li>

  <li>
    <p>Browser engine fixes</p>
  </li>

  <li>
    <p>Improved malware detection</p>
  </li>

  <li>
    <p>Better content blocking rules</p>
  </li>
</ul>

<p>Comet updates automatically in the background.</p>
