Privacy Policy for Auto Volume Normalizer

Effective Date: 2025-08-26
Version: 1.2.0

Extension: Auto Volume Normalizer
Developer: Vitalii Tereshchuk (xVoLAnD)

Summary

Auto Volume Normalizer does not collect, store, or transmit any personal data, browsing history, audio content, or user identifiers. All audio processing happens locally in your browser. No analytics, no tracking, no telemetry — not even anonymous.

Permissions Used

Permission	Purpose
`storage`	Saves your settings (target volume, max boost, attack/release, compressor, preset) locally in your browser via `chrome.storage.local`
`host_permissions: <all_urls>`	Allows the extension to inject audio processing into any web page containing `<audio>` or `<video>` elements

No other permissions are requested.

Data Processing

All audio processing occurs locally using the browser's built-in Web Audio API (AudioContext, AnalyserNode, GainNode, DynamicsCompressorNode)
No audio data leaves your device — the extension creates a processing graph attached to each media element; audio never touches a network
No analytics, tracking, or telemetry — the extension makes zero network requests
Settings only — stored via chrome.storage.local, accessible only by this extension
Debug panel (optional, toggled via Ctrl+Shift+V or popup button) displays real-time metrics only in your browser — nothing is logged, stored, or transmitted

Third Parties

None. The extension has:

No external dependencies
No network requests
No third-party services
No CDNs, no analytics providers, no crash reporters

Data Retention

Settings persist until you uninstall the extension or clear browser data
No data is stored on any server
Uninstalling the extension removes all local data automatically

Your Rights

Since no personal data is collected, there is nothing to access, rectify, delete, or port. You control all settings directly in the extension popup.

If this policy changes, the updated version will be:
