OWSH Speed Audit Extension Privacy Policy

Last updated: Feb 15 2026

1. Data Collection

The OWSH Site Performance Checker browser extension does not collect, store, or transmit any personal data or browsing information. All performance analysis happens entirely within your browser.

2. How the Extension Works

  • All performance analysis is performed locally using browser Performance APIs.
  • No data is sent to external servers for analysis.
  • No cookies are set.
  • No tracking or analytics of any kind.
  • No account or login required.

3. What the Extension Analyzes

When you click the extension icon, it analyzes the current page's performance using browser APIs:

  • Core Web Vitals (LCP, CLS, INP)
  • Navigation timing
  • Resource loading (scripts, CSS, images, fonts)
  • Image optimization (dimensions, lazy loading, formats)
  • Render-blocking resources
  • Long tasks (>50ms)
  • Font loading
  • Connection info
  • DOM node count
  • Third-party vs first-party resources

This analysis is performed entirely in your browser. No page content is transmitted anywhere.

4. Permissions Explained

  • activeTab: Required to analyze the current webpage's performance when you click the extension icon. The extension can only access the tab you're viewing and only when you activate it.
  • scripting: Required to inject the analysis script that measures performance metrics and inspects resource loading on the page.

5. Network Requests

The extension makes no network requests. All analysis is performed locally using the browser Performance APIs and page content already loaded in your browser. No data is sent to OWSH servers or any third party.

6. External Links

The extension provides optional links to external resources:

  • Full Performance Report: Opens audit.owshsystems.com/performance with the current page URL for more detailed analysis.
  • OWSH Systems: Links to our main website for information about other tools.

Clicking these links is entirely optional and requires user action.

7. Updates

This privacy policy may be updated from time to time. Any changes will be reflected on this page with an updated "Last updated" date. The extension will always maintain its commitment to local-only analysis with no data collection.
