Privacy Policy

Last Updated: February 23, 2026

1. Introduction

At NavGraph, we take your privacy seriously. This Privacy Policy outlines how our Chrome extension and website handle data. Our core philosophy is local processing: your data stays on your machine.

2. Data Collection & Usage

NavGraph does not collect, store, or transmit any personal information or browsing history to external servers.

  • Web History: The extension reads the URL of the current page only to locate and visualize its sitemap. This data is processed strictly locally in the extension's memory.
  • User Activity: Clicks on nodes within the graph are used solely to trigger navigation in your browser tab.
  • Website Content: The extension extracts hyperlinks from the current webpage to generate the visual model of the site's hierarchy. This extraction happens locally.

3. Local Processing

All program logic, including the visualization engine (D3.js), is bundled locally within the extension package. No code is loaded from remote servers, and no data is sent to us or any third party.

4. Third Parties

Since we do not collect any data, no data is shared, sold, or transferred to third parties.

5. Permission Justifications

For transparency, here is why we require certain browser permissions:

activeTab
Required to identify the URL of the currently active tab to fetch the correct sitemap.
scripting
Used to extract anchor tags from the active webpage to build the graph visualization.
Host Permission (<all_urls>)
Necessary to fetch sitemap.xml files via Cross-Origin requests from the root of the domains you visit.
