# Control what Comet Assistant can use

<h2 id="h_6fed9a0c2b">How do I control what Comet has access to?</h2>

<p>Comet gives you full control over what the Assistant can see and act on.<br />Manage access anytime in <b>Settings → Privacy and security</b>:</p>

<ul>
  <li>
    <p><b>Comet Assistant</b> — allow or prohibit Comet to access your browser history, navigate the web, and interact with sites</p>
  </li>

  <li>
    <p><b>Block tasks on specific websites</b> — add sites you don’t want Comet to use for AI actions or context</p>
  </li>
</ul>

<p>For example, you can block your bank’s website so Comet won’t use that page for any tasks or suggestions.</p>

<hr />

<h2 id="h_4b9655c43e">How Comet Assistant uses your data</h2>

<ul>
  <li>
    <p><b>Your data stays on your device by default.</b> All browsing data, including visited sites and cookies, is stored locally.</p>
  </li>

  <li>
    <p><b>Comet only sends minimal context to Perplexity</b> when needed to complete a request (e.g., summarizing an open tab or booking a service).</p>
  </li>

  <li>
    <p><b>You control integrations.</b> If Comet needs access to another service (like Gmail), it will always ask for approval first.</p>
  </li>

  <li>
    <p><b>Comet never has access to your passwords or payment data</b>.</p>
  </li>
</ul>

<hr />

<h2 id="h_f965aa0488">Tips</h2>

<ul>
  <li>
    <p>You can always pause Assistant’s access or block specific sites anytime.</p>
  </li>

  <li>
    <p>For fully private sessions, use <b>Incognito mode</b>, which prevents Assistant from indexing your browsing activity.</p>
  </li>
</ul>
