Tab Muter is a Chrome extension that re-adds a way to access the “Mute Tab” feature, which used to be available in Chrome itself.
The bottom line: Tab Muter does not deliberately collect or transmit any personal data.
The only data that is persistently stored by Tab Muter is your preferred icon colour (if configured in the extension options), which is stored in Chrome’s synced settings storage.
In certain circumstances (e.g. when “debug mode”, found in the extension options, is enabled), some information about your computer or browser might be logged (for example, the size of the browser window, or in rare cases the IDs of other extensions you have installed). Tab Muter never sends these logs to anyone. If you are experiencing problems with the extension and ask me for support, I might ask you to copy the logs into a bug report; you always have the option not to do this, if you are for any reason uncomfortable sharing that information.
Download Tab Muter on the Chrome Web Store.
