No data collection
VolMaster collects no personal data. It does not track, profile, or transmit any information to any server, ever.

Local storage only
Your volume settings are saved to your browser's local extension storage (storage.local). This data never leaves your device.

Tab metadata
Tab titles, URLs, and favicons are read to display your tabs in the popup. This data is used only within the popup and is never stored or transmitted.

No network requests
VolMaster makes zero network requests. There are no analytics, no crash reporters, no update servers, and no external dependencies of any kind.

No third parties
The extension is entirely self-contained. No third-party code or services are used.
