Frequently Asked Questions
Is it really free?
Yes, completely free with no premium features, usage limits, or hidden costs.
Do you send my data to any server?
Not automatically. All analysis runs 100% locally in your browser, with no tracking, analytics, or telemetry. The only exception is manual: if you click the “Report” button, a page opens on uxr.cl with your analysis results encoded in the URL. Nothing leaves your browser unless you ask for it.
What does the “Report” button do?
It's a manual action that generates a shareable report of your analysis. When clicked, the extension encodes the results (analyzed URL, scores, and metrics) into the address and opens the report page on uxr.cl. That's the only time your analysis data leaves the browser, and only when you choose to.
How complete is the analysis?
It's a deterministic diagnosis: it applies rules and heuristics to the HTML and DOM of the page loaded at that moment. It does not crawl the whole site, use real field data or AI models, and some signals (such as E-E-A-T) are pattern-based approximations. It's a fast, actionable guide — not a replacement for a full manual audit.
Can I use the extension on internal sites or localhost?
Yes, the extension works on any URL, including localhost, local IPs, corporate intranets, sites behind VPN, and private staging environments.
