Privacy Policy

Effective Date: July 27, 2026

Introduction

Volume Master Max ("we," "our," or "us") is committed to respecting and protecting user privacy. This Privacy Policy explains how our Chrome browser extension operates on a strict, client-side, zero-telemetry architecture.

Zero Data Collection Guarantee: Volume Master Max does not run remote analytics servers, track your browsing behavior, or send audio data or personal information to external servers.

Information Handling & Local Processing

1. Audio Streams & Processing

Volume Master Max processes audio streams from browser tabs to provide volume amplification (up to 600%), equalizer controls, and per-tab volume management.

  • Local Web Audio Processing: Audio streams captured via tabCapture and processed in offscreen documents are routed strictly through local Web Audio API nodes (AudioContext, GainNode, and BiquadFilterNode).
  • No Audio Storage: Audio streams are processed in real-time on your local device. Audio data is transiently processed and is never recorded, logged, saved, or transmitted anywhere.

2. User Configuration & Preferences

Volume Master Max allows users to customize their extension preferences (such as dark mode, scroll direction, and equalizer preset selections).

  • Where it is stored: Preferences are stored exclusively inside your browser's local storage (chrome.storage.local).
  • No External Access: Saved preferences stay entirely on your local browser and are never transmitted off your device.

Third-Party Services & Remote Code

Volume Master Max operates 100% offline. We do NOT use any remote code, external scripts, third-party APIs, or analytics frameworks. All code executing within the extension is packaged locally.

Browser Permissions Justification

Volume Master Max requests only the minimal browser permissions necessary to provide its core functionality:

  • activeTab & tabs: Detects tabs playing audio, displays tab titles and favicons, and allows per-tab volume adjustment.
  • tabCapture & offscreen: Routes audio streams locally through Web Audio API nodes for volume amplification up to 600% and equalization.
  • storage: Stores extension preferences locally on your browser.

Developer Policy Certifications

In accordance with the Chrome Web Store Developer Program Policies:

  • We do NOT sell or transfer user data to third parties.
  • We do NOT use or transfer user data for purposes unrelated to the extension's single purpose.
  • We do NOT use or transfer user data for creditworthiness or lending purposes.

Changes to This Policy

We may update our Privacy Policy periodically. Updates will be posted directly to this page with a revised Effective Date.
