The short version: Volume Booster processes all audio locally on your device and does not collect, track, sell, or share any of your data. No accounts, no analytics, no ads.
This Privacy Policy explains how the Volume Booster browser extension ("Volume Booster", "we", "our") handles information. Volume Booster is designed to be private by design: it boosts and equalizes the audio of your browser tabs entirely on your own device.
None
Volume Booster does not collect, transmit, sell, or share any personal information, browsing data, or audio. Specifically:
All audio boosting and equalization happens locally, in real time, using your browser's built-in Web Audio technology inside a hidden offscreen document. Your audio is never recorded, stored, or uploaded. When you stop boosting a tab, its audio returns to normal and nothing is retained.
To make the extension useful, the following is saved only in your browser's local storage
(chrome.storage.local) and is never transmitted anywhere. You can erase it at
any time.
| What | Why |
|---|---|
| Per-site volume, equalizer, preset & mute settings | Restore your sound when you return to a website |
| Custom presets you create | So you can reuse them |
| Your preferences (theme, maximum boost, startup behavior, etc.) | Remember how you like the extension set up |
Volume Booster does not keep any browsing history — it stores no list of the sites you visit. You can remove everything above at any time from Settings → Reset all settings, or by uninstalling the extension.
Each permission is used only to make Volume Booster work, and never to gather data:
| Permission | Why it's needed |
|---|---|
tabCapture |
Capture a tab's audio so it can be boosted and equalized (processed on-device) |
offscreen |
Run the real-time audio engine that a service worker cannot host |
storage |
Save your settings locally on your device |
tabs / activeTab |
Identify the current tab and apply the boost to it |
Volume Booster requests no host permissions and cannot read the content of the web pages you visit — only the audio you explicitly choose to boost.
We do not sell or transfer your data to third parties. We do not use or transfer your data for any purpose unrelated to the extension's single purpose, and never to determine creditworthiness or for lending purposes. Because no data is collected, there is nothing to share.
Volume Booster does not knowingly collect any information from anyone, including children.
If this policy changes, the updated version will be posted here and the "Last updated" date above will be revised.
