In-depth safety analysis
This extension requests the "activeTab" and "scripting" permissions. This means it can run code to read and modify the content of whichever web page you are actively viewing, but only after you click the extension's icon or invoke it. For a digital ruler tool, this permission scope is necessary to draw measurement lines on the page and is appropriately minimal for its function.
General browser utilities like measurement tools are typically low-risk, but users should always be cautious about granting any extension the ability to interact with page content. A careful user should know that an extension in this category could theoretically read sensitive information displayed on the current page when activated, so it’s wise to avoid using it on pages showing passwords, financial details, or other private data.
According to the fact sheet, this extension’s strongest dimension is its minimal and focused permission request, which aligns well with its stated purpose. Its weakest dimension is "Maintenance & Ownership," rating very low, which generally indicates a lack of clear public information about the publisher or infrequent updates. This combination suggests that while the code itself may ask for little, the developer's long-term commitment and transparency are unclear.
