Privacy Policy

Last updated: January 2024

Overview

Green Coding Score ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how our Chrome extension handles information when you use our service.

The most important thing to know: Green Coding Score operates entirely locally on your device. We do not collect, store, or transmit any personal data or browsing information to external servers.

Information We Do NOT Collect

Green Coding Score does not collect:

  • Personal identification information (name, email, address, etc.)
  • Browsing history or URLs you visit
  • Website content or page data
  • Cookies or tracking identifiers
  • IP addresses or location data
  • Any usage analytics or telemetry

How the Extension Works

When you visit a website, Green Coding Score:

  • Analyzes the page's performance metrics using your browser's built-in APIs (Resource Timing API, Performance API)
  • Calculates a sustainability score based on transfer size, request count, third-party ratio, and load time
  • Displays the score on the extension badge and popup
  • Generates recommendations for improvement

All of this processing happens entirely within your browser. No data leaves your device.

Data Storage

The extension may temporarily store calculated scores in your browser's local storage to display them in the popup. This data:

  • Is stored only on your local device
  • Is never transmitted to any external server
  • Can be cleared by uninstalling the extension or clearing browser data

Third-Party Services

Green Coding Score does not integrate with any third-party analytics, advertising, or tracking services. We do not share any information with third parties because we do not collect any information in the first place.

Permissions

The extension requires certain browser permissions to function:

  • activeTab: To analyze the current page's performance metrics
  • storage: To temporarily store scores locally for display purposes

These permissions are used solely for the extension's core functionality and not for data collection.

CLI Tool and API

If you use the command-line tool or programmatic API:

  • URLs you analyze are processed locally using Puppeteer (headless Chrome)
  • Results are stored only where you specify (e.g., local files)
  • No data is sent to our servers or any third-party services

Open Source

Green Coding Score is open source software licensed under Apache 2.0. You can review our entire codebase on GitHub to verify our privacy practices.

Children's Privacy

Our extension does not collect any personal information from anyone, including children under 13 years of age.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. Since we don't collect any contact information, we cannot notify you directly of changes, so please review this policy periodically.
