Privacy Policy
Volume Booster does not collect, store, or transmit any user data. There is no account, no analytics, no advertising, and no server. Everything the extension does happens locally in your browser.
Who this policy is from
Volume Booster is developed and published by Md Ruman Hossain, an individual developer. Contact: ruman.cst.bd@gmail.com.
What the extension does
Chrome provides no API for changing a tab's volume directly. When you set a boost level, Volume Booster runs a small script in the page you are on that routes its video and audio elements through a Web Audio gain stage and a limiter before they reach your speakers.
Some pages keep their video where that script cannot reach it. Only in that case does the extension fall back to capturing the tab's audio, applying the same gain and limiter, and playing it straight back.
This processing happens entirely inside your browser, in memory. The audio is never recorded, never written to disk, and never sent anywhere. The script runs only on the tab you act on, only after you choose a level in the popup, and it reads nothing from the page apart from its media elements.
Data collected
None. Specifically, the extension does not collect:
- Personally identifiable information — name, address, email, age, or ID numbers
- Health information
- Financial or payment information
- Authentication information — passwords, credentials, or PINs
- Personal communications — emails, texts, or chat messages
- Location, including IP-derived location
- Web history or browsing activity
- User activity — clicks, mouse position, scrolling, or keystrokes
- Website content — text, images, sounds, videos, or hyperlinks
Information stored on your device
The extension stores one thing locally: the boost percentage you have
set for each open tab, so the popup can show the current level when you
reopen it. This is kept in Chrome's
chrome.storage.session area, which lives on your own
machine and is cleared automatically when you close the
browser. It is never transmitted off your device.
Permissions and why they are needed
| Permission | Why it is required |
|---|---|
activeTab |
Grants temporary access to the tab you are on, and only at the moment you open the popup and choose a level. It gives no standing access to any site. |
scripting |
To run the small audio script in that tab. The script only adjusts the volume of media elements already on the page. |
tabCapture |
The fallback for pages the script cannot reach. The audio of the tab you chose is amplified and played straight back; it is never recorded, stored or sent anywhere. |
offscreen |
Manifest V3 service workers cannot use the Web Audio API. An offscreen document applies the gain and limiter to captured audio. |
| Access to a site (optional) | Never requested at install. Some sites keep their video inside an embedded frame the extension cannot otherwise reach; on those, the popup offers a button to grant access so the volume can be adjusted in the page instead of by capturing the tab. You can decline, and you can withdraw it later in Chrome's extension settings. It is used only to adjust audio. |
storage |
To remember the boost level per tab for the current browser session. |
tabs |
To identify which tab is active so the boost is applied to the right one, and to release it when a tab is closed. |
Third parties
The extension contains no analytics, no tracking, no advertising, and no third-party libraries or remote code. It makes no network requests. No data is sold or transferred to third parties, used for purposes unrelated to amplifying tab audio, or used to determine creditworthiness or for lending purposes.
Children
The extension is not directed at children and collects no data from anyone, regardless of age.
Changes to this policy
If this policy changes, the updated version will be published at this same address with a revised date. Material changes will also be noted in the extension's Chrome Web Store listing.
