In-depth safety analysis
This extension requests only the "storage" permission, which allows it to save and retrieve data locally in your browser — such as loop start and end times or other preferences. It cannot read or modify content on YouTube or any other website, and it has no access to your browsing history. For a tool that simply loops YouTube videos, this permission scope is minimal and entirely expected.
As with any browser extension, especially those that interact with popular platforms like YouTube, a careful user should consider the publisher’s reputation and the extension’s update history. While this extension’s permission set is safe, the general category can attract copycats or extensions that later request broader access. Always review an extension’s requested permissions and be cautious if they change unexpectedly.
In the safety assessment, the strongest dimension is Maintenance & Ownership, reflecting that the extension is actively updated (version 5.18.2, manifest V3) and well-maintained. The weakest dimension is Publisher & Identity, indicating that the developer (alvinhkh.com) is an individual or small entity without extensive public verification. This is common for indie extensions and does not signal a problem, but users who prefer large, well-known publishers may note it.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.

Who's Behind Looper for YouTube?
- Publisher alvinhkh.com
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.
