Volume Booster does not transmit any data, sell any data, or share any data with anyone. Nothing leaves your device.

WHAT IS STORED

One thing: a list of website origins and the volume level you chose for each, for example https://www.youtube.com -> 240%, along with a timestamp used to drop the oldest entry once 300 sites are stored. It is kept in the browser's own extension storage on your device.

Nothing else is stored. No page content, no audio, no identifiers, no usage statistics, no clicks or keystrokes.

That list only ever contains sites where you deliberately changed the volume. Sites you visit without touching the slider are never recorded.

WHAT IS TRANSMITTED

Nothing. The add-on makes no network requests. It has no server, no analytics, no error reporting, and no remote configuration. Its build fails if fetch, XMLHttpRequest, WebSocket, eval, or importScripts appear anywhere in the shipped code, so this is enforced rather than promised.

PERMISSIONS

storage: saves your level for each site so it comes back when you return. Stays on your device.
activeTab: lets the popup see which tab you are on so the level goes to the right one. Access ends when the popup closes.
scripting: applies the control to a tab that was already open before the add-on was installed.

The add-on does not request the tabs permission, host_permissions, or tab audio capture.

DELETING YOUR DATA

"Reset all" in the popup erases every stored site level. Removing the add-on deletes its storage entirely.
