Very helpful ext.
DANGER!!!! Serious privacy concerns: collects far more than “website content” I installed/reviewed WhatRuns because it claims to identify technologies used on websites, but the extension’s behavior appears much broader than what the Chrome Web Store disclosure and privacy policy suggest. The policy describes collecting “source code snippets and public resources” only to identify technologies. In the code, however, content.js captures document.documentElement.outerHTML, which is the full page HTML, not just snippets. More concerning: the extension appears to scrape the user’s email and API key from the WhatRuns dashboard and attach them to reports when logged in. That directly links collected browsing/page data to an identifiable user, despite policy language saying collected data is anonymized and not linked to personal browsing histories. It also sends the full current URL and appears to keep a local buffer of visited hosts, then bulk-posts that data. That looks like browsing history collection, not just “website content.” The Chrome Web Store disclosure says “Data collected: Website content,” but based on the code, it also appears to collect visited URLs, email, and authentication-related data. Users should be aware that this may be far more invasive than advertised. Users can verify this themselves by inspecting the extension files locally. In Chrome, go to chrome://extensions, enable Developer mode, find WhatRuns, copy its ID, then open the extension folder on your computer and inspect files like content.js and background.js. Search for terms such as outerHTML, location.href, email, api_key, appendUserDetails, and bulk upload endpoints. You can also use Chrome DevTools’ Network tab while browsing to see what data the extension sends out. I would not recommend installing this extension unless the developer clearly explains this behavior, updates the disclosures, and stops linking collected site data to identifiable users.
very good
