What Chrome asks you to allow

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

• Read and change your data on heyzine.com, all heyzine.com sites, and cdnc.heyzine.com
• Manage your downloads

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://heyzine.com/* only heyzine.com
• https://*.heyzine.com/* heyzine.com and all its subdomains
• https://cdnc.heyzine.com/* only cdnc.heyzine.com

Pages it runs its code on

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

• https://heyzine.com/* only heyzine.com
• https://*.heyzine.com/* heyzine.com and all its subdomains

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.

Who publishes it
