What Chrome asks you to allow

- Read and change your data on app.marcusfacilities.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.

Routine for an extension
Pages it runs its code on
It runs its own code on specific pages only: 1 site pattern.
https://app.marcusfacilities.com/extension/*only app.marcusfacilities.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.

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.
