The developer also certifies that your data is not sold to third parties outside approved uses, not used for purposes unrelated to the extension's core function, and not used to decide creditworthiness or lending.

What Chrome asks you to allow

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

Every site you visit. This extension can read and change the content of any page you open. What access to every site means

Routine for an extension

Pages it runs its code on

It runs its own code on every page you open: the manifest declares a content script for all sites.

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.

Sites that can connect to it

Web pages matching these patterns can open a messaging channel to it: 1 site pattern.

Declared as externally connectable in the manifest: a page on these sites can exchange messages with the extension, for example to tell it you have signed in. It does not give the page access to your browser.

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.

Who publishes it
