Anchor Text Checker collects no data and makes no network requests. When you click "Check This Page", it reads the links on the current tab (via the activeTab and scripting permissions) purely to classify their anchor text locally inside the extension. No page content is sent anywhere.
Your per-site brand and keyword settings and your most recent report are saved in your browser's local storage so they persist between uses. This data stays on your device and is not accessible to the developer.
