In-depth safety analysis
This extension requests only the "storage" permission, which allows it to save your preferences (like your favorite time zones) locally in your browser. It does not ask for access to your browsing history, tabs, or the content of websites you visit. For a time zone converter, this is a minimal and expected permission scope, as the tool needs to remember your settings but has no reason to read or modify web pages.
General-purpose browser extensions in this category are typically safe, but users should be aware that any extension can be a target for impersonation or cloning. When installing tools that handle location data, it is wise to verify you are using the official version from a trusted publisher. The developer declares they collect location information, which is normal for a time zone converter that may auto-detect your zone, but you should review the privacy policy to understand how that data is handled.
Based on the fact sheet, this extension scores highly on permissions and access, meaning it uses only the bare minimum capabilities needed to function. The weakest dimension is publisher and identity, which suggests there may be limited public information about the developer or their track record, though this does not indicate any wrongdoing.
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.
