Domain Collector Nexus respects your privacy. This extension is designed to operate entirely within your browser and does not collect, store, transmit, or share any personal data.

<code>Data Collection
</code>

The extension does not collect any personally identifiable information (PII).

It only processes domain names that your browser connects to, and this information is stored temporarily in your local browser memory for display purposes only.

<code>Data Storage

All collected domain information is kept locally within your browser.

No data is ever sent to external servers or shared with third parties.

<code>Permissions
</code>

The permissions requested (e.g., webRequest, tabs, and storage) are solely used to detect and display domain activity.

These permissions do not grant the extension access to your personal information, browsing history, or account data.

<code>Third-Party Services
</code>

This extension does not use any analytics, tracking, or advertising services.

<code>User Control
</code>

You may clear all collected domain data at any time using the built-in “Clear” button.

Uninstalling the extension will automatically remove all associated local data.

<code>Contact
</code>
