In-depth safety analysis
FocusGuard requests a broad set of permissions that include access to all websites (*://*/*), the ability to read and interact with browser tabs, and the use of storage, alarms, and notifications. For a site blocker, this level of access is expected—the extension must be able to inject blocking scripts on any page you visit, manage block lists, and send you reminders. The offscreen and favicon permissions are less common but may support background tasks like rules processing or custom block-page icons. Overall, the permission scope aligns with what most site‑blocking tools require to function properly.
As with any extension that can read and alter all your web activity, a careful user should ensure they trust the publisher. Site blockers have a high‑privilege design by nature, so you are handing over the ability to see everything you browse. This category is generally considered low‑risk when the extension comes from a reputable developer and is transparent about its data practices. In this case, the developer has declared that data is not sold or used for unrelated purposes, and the privacy dimension scored a perfect 100, which suggests the declared practices are privacy‑friendly.
The fact sheet shows a high overall safety grade (A), with the strongest dimension being Maintenance & Ownership (100%), indicating the extension is actively maintained and recently updated. The weakest dimension is Publisher & Identity (60%), which may reflect limited public information about the developer or incomplete verification. While this does not indicate anything wrong, users who are especially cautious could look further into the publisher before installing.

- Publisher Block Site
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.
