In-depth safety analysis
This extension asks for only two permissions, both quite limited. The "activeTab" permission lets it see the URL and page content of the tab you are currently on, but only after you click the extension's icon. The "storage" permission allows it to save settings locally on your device. This is a very minimal and tightly focused scope for a general browser tool, and it does not request broad access to all websites or browsing history.
General browser extensions that interact with the current page can sometimes be used to alter what you see, and users should always verify that an extension comes from its authentic publisher. For a tool like this, it is wise to check that its behavior after activation matches its stated description and that it does not insert unexpected content or redirect you.
The fact sheet shows a high safety score of 94 out of 100. The strongest dimension is maintenance and permissions, indicating the extension is well-scoped and kept current. The weakest dimension is publisher identity, which has a moderate score. This often reflects limited publicly verifiable background about the developer, which is common for smaller or independent publishers and generally worth noting as a careful user.

Who's Behind Cat Gatekeeper?
- Publisher cat-gatekeeper.app
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
