Detection is pattern-based: known token formats, key=value secrets, credentials in URLs, private key blocks, and optional high-entropy strings. It will miss secrets that look like ordinary words. Read the output before you share it.

The only network request this page can make is the URL you ask it to fetch. Your text and the result stay in this tab's memory. Rule choices are saved in localStorage.
