What Chrome asks you to allow

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

• Read and change your data on leetcode.com
• Display notifications

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

No site access is declared in the manifest, so it cannot read the pages you open on its own.

Routine for an extension

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

Pages it runs its code on

It runs its own code on specific pages only: 1 site pattern.

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.
