Is MuteDeck safe to install?

What data it declares

What Chrome asks you to allow

When you add it, Chrome asks you to allow it to:

• Read and change your data on a number of websites
• Read your browsing history

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

What it can reach

Specific sites only: 24 match patterns.

• https://meet.google.com/* only meet.google.com
• https://app.zoom.us/* only app.zoom.us
• https://teams.microsoft.com/* only teams.microsoft.com
• https://teams.microsoft.com.mcas.ms/* only teams.microsoft.com.mcas.ms
• https://streamyard.com/* only streamyard.com
• https://riverside.fm/* only riverside.fm
• https://riverside.com/* only riverside.com
• https://meet.jit.si/* only meet.jit.si

• https://whereby.com/* only whereby.com

Reaches your browsing data or every site

• See the address and title of every tab you have open tabs

Worth knowing

• Run its own code on the pages it can access scripting

Routine for an extension

• Act on the current tab, but only after you click it activeTab
• Store data in your browser storage

Pages it runs its code on

It runs its own code on specific pages only: 24 site patterns.

• https://meet.google.com/* only meet.google.com
• https://app.zoom.us/* only app.zoom.us
• https://teams.microsoft.com/* only teams.microsoft.com

A content script is code the extension injects into pages matching these patterns. On those pages it can read and change what you see, whether or not a host permission is listed above.

What it may ask for later

Not granted when you add it: Chrome asks you the moment the extension requests one of these, and you can refuse. It may later ask for access to every site.

• https://*/* every site
• http://*/* every site
