If you still have it installed

A listing leaving the store does not by itself remove the extension from browsers that already have it. If you still have it, you can see what it can reach and remove it in a minute:

1. Type chrome://extensions in the address bar and find the extension in the list.
2. Open its details. The site access setting shows where it can run; set it to run only on click and it reaches a page only after you press its icon.
3. To uninstall it, choose Remove on the same page.

• Authentication information such as passwords, credentials or PIN codes
• Personal communications such as emails, texts or chat messages
• User activity such as clicks, scrolling, keystrokes or network monitoring

This is the developer's own declaration in the Chrome Web Store. We cannot check it against what the extension does.

What Chrome asks you to allow

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

• Read and change your data on unityroom.com and omezi42.github.io
• 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

Specific sites only: 2 match patterns.

• https://unityroom.com/games/anokorotcg* only unityroom.com
• https://omezi42.github.io/* only omezi42.github.io

Worth knowing

• Run its own code on the pages it can access scripting

Routine for an extension

• 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.

• https://unityroom.com/games/anokorotcg* only unityroom.com

What the store shows

The listing is no longer in the store, so none of the store's badges apply to it now.

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

The store lists no publisher name. This listing has been in the store since 2025-07-30 and was last updated on 2025-07-30.
