In-depth safety analysis
This extension requests only the "storage" permission, which allows it to save settings or data locally on your device. For a JSON viewer, this is a minimal and expected permission scope, likely used to remember your formatting preferences. It cannot read or modify the content of websites you visit unless you explicitly interact with it on a page containing JSON.
General browser extensions like JSON viewers typically pose a low inherent risk, but a careful user should be aware that any extension that formats page content could theoretically be updated to alter how data is displayed. It is good practice to confirm that the formatting matches the raw data for sensitive information. The developer has declared that data is not sold or used for unrelated purposes, which is a positive signal, though these are self-reported claims.
The strongest dimension in the fact sheet is "Permissions & Access," reflecting the extension's minimal and appropriate permission request. The weakest is "Maintenance & Ownership," which received a very low score. This often indicates factors like a lack of a clear privacy policy, a short update history, or limited public information about the publisher, which can be a consideration for long-term reliability and support.
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 JSON Viewer?
- Publisher Rongjian Zhang
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.
