Is Broken Link Checker safe?

Checks links on the current page and highlights valid, broken, and redirected URLs.

This extension scans URLs on the webpage you have open and color-codes the results: green for valid links, red for errors, and blue for redirects. It provides filters by status and can export a CSV report with link text, URL, HTTP status code, and status description. The store description says checks run locally in the browser with no external service.
