What Chrome asks you to allow

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

• Read and change your data on www.youtube.com, youtu.be, and m.youtube.com

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: 3 match patterns.

• https://www.youtube.com/* only www.youtube.com
• https://youtu.be/* only youtu.be
• https://m.youtube.com/* only m.youtube.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 the store shows

Has it asked for more over time?

This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.

The permissions this extension requests have not changed since we started watching it.
