What Chrome asks you to allow

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

• Read and change your data on gmail.googleapis.com, mail.google.com, and prosignature.co

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: 1 match pattern.

• https://gmail.googleapis.com/* only gmail.googleapis.com

Worth knowing

• Sign you in with a Google account identity

Routine for an extension

• Schedule work to run later alarms
• Store data in your browser storage

Pages it runs its code on

It runs its own code on specific pages only: 2 site patterns.

• https://mail.google.com/* only mail.google.com
• https://prosignature.co/* only prosignature.co

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.

• https://prosignature.co/* only prosignature.co

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.
