Privacy Policy

1. Introduction

This Privacy Policy describes how GreenGo Helper ("the Extension", "we", "us", or "our") handles information when you use our browser extension. GreenGo Helper is a companion extension for the GreenGo desktop application that enables one-click audio analysis and processing.

Our Privacy Commitment: GreenGo Helper is designed with privacy as a core principle. We do not collect, store, transmit, or share any of your personal data. All data processing happens locally on your device.

2. Information We Do NOT Collect

GreenGo Helper does NOT collect, store, or transmit any of the following:

• Personal identification information (name, email, address, phone number)
• Browsing history or web activity outside of supported sites
• Viewing history or watch patterns on any site
• Search queries or preferences
• IP addresses or location data
• Device information or browser fingerprints
• Analytics, telemetry, or usage statistics
• Crash reports or error logs

We have no servers. There is no backend infrastructure, no database, and no remote data collection of any kind. The extension operates entirely on your local machine.

3. Data Processed Locally

GreenGo Helper processes the following data locally on your device only to provide its core functionality:

3.1 Session Data

What: Authentication data from supported sites that you are logged into.

Why: This data allows the GreenGo desktop app to access content on your behalf using your existing sessions.

Where: Session data is stored locally on your computer only.

Transmission: Session data is sent only to localhost:7291 (the GreenGo desktop app running on your own computer). It is never transmitted to any remote server.

3.2 Audio URLs and Metadata

What: The URL and title of audio you choose to send to GreenGo for analysis.

Why: To send processing requests to the GreenGo desktop app.

Where: This information is stored temporarily in:

• The extension's local storage (Chrome Storage API)
• A local queue file: ~/Downloads/greengo_queue.json

Transmission: URLs are sent only to localhost:7291 (your local GreenGo app). They are never transmitted to any remote server.

3.3 Processing Queue

What: A list of audio items you've queued for processing when GreenGo was offline.

Why: To ensure audio is processed even if the GreenGo app isn't running when you click the send button.

Where: Stored locally in the extension's Chrome Storage and in ~/Downloads/greengo_queue.json.

Retention: Queue items are deleted automatically after they're successfully processed by GreenGo, or when you manually clear the queue.

4. Permissions Explained

GreenGo Helper requests the following browser permissions. Here's exactly why each one is needed:

5. Network Communication

GreenGo Helper communicates only with the GreenGo desktop app running on your local machine. All communication happens over localhost (127.0.0.1) on port 7291.

5.1 Local API Endpoints

The extension connects to these endpoints on your computer:

• http://localhost:7291/ping — Health check to detect if GreenGo is running
• http://localhost:7291/download — Send audio processing requests
• http://localhost:7291/cookies — Sync session data to GreenGo
• http://localhost:7291/queue — Retrieve current processing queue status

5.2 No External Servers

GreenGo Helper does NOT connect to:

• Any remote servers operated by us or third parties
• Analytics services (Google Analytics, Mixpanel, etc.)
• Advertising networks
• Content delivery networks (CDNs) for tracking
• Error reporting services (Sentry, Bugsnag, etc.)

The only external domains the extension interacts with are supported audio sites (to inject the send button and read session data), and this interaction is limited to what's necessary for the extension to function.

6. Data Retention

• Session Data: Updated automatically whenever you visit supported sites. Stored until you uninstall the extension or manually delete the data file.
• Processing Queue: Cleared automatically when audio is successfully processed, or when you click "Clear Queue" in the extension popup.
• Extension Settings: Stored in Chrome's local storage until you uninstall the extension.

7. Data Sharing

We do not share any data with anyone. There is no data to share because we don't collect any data in the first place.

The extension does not integrate with:

• Third-party analytics providers
• Advertising networks
• Social media platforms
• Data brokers or aggregators

8. Third-Party Services

GreenGo Helper does not use any third-party services, libraries, or SDKs that collect data. The extension is built using only:

• Standard browser APIs (Chrome Extension APIs)
• Vanilla JavaScript (no external frameworks that track users)
• Local file system operations

9. Children's Privacy

GreenGo Helper does not knowingly collect any information from anyone, including children under 13. Since we don't collect any data at all, the extension is safe for users of all ages.

10. Data Security

Since all data processing happens locally on your device, the security of your data depends on:

• Your device's security (password protection, disk encryption, etc.)
• Your browser's security (keeping Chrome/Firefox updated)
• File system permissions on your computer

We recommend:

• Keeping your operating system and browser up to date
• Using strong passwords and enabling disk encryption
• Only installing the extension from official sources (Chrome Web Store, Firefox Add-ons)

11. Your Rights and Control

You have complete control over your data:

11.1 View Your Data

• Session data: Check the GreenGo app data folder on your system
• Queue: Open ~/Downloads/greengo_queue.json
• Extension storage: Use Chrome DevTools → Application → Storage → Extensions

11.2 Delete Your Data

• Clear queue: Click "Clear all" in the extension popup
• Delete session data: Delete the session file from the GreenGo app data folder
• Remove all data: Uninstall the extension from chrome://extensions

11.3 Opt Out

If you don't want the extension to capture session data or send processing requests, simply uninstall it. There are no background processes or residual tracking after uninstallation.

12. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in the extension's functionality or legal requirements. When we make changes:

• The "Last Updated" date at the top of this page will be revised
• Significant changes will be announced on the GreenGo website
• Continued use of the extension after changes constitutes acceptance of the updated policy

We will never introduce data collection or tracking without explicit notice and user consent.

13. Open Source

GreenGo Helper's source code is available for review. You can inspect exactly what the extension does by:

• Viewing the source code in the Chrome Web Store (click "View source")
• Inspecting the unpacked extension files after installation
