CertGrab collects no data. It has no analytics, no accounts, no tracking, and it never transmits anything to us or to anyone else. The extension makes no network requests at all.
When you invoke it (toolbar click or keyboard shortcut), CertGrab captures the visible area of the page you are on, lets you drag a box over a certification number, and reads the digits inside that box using an OCR engine (Tesseract) that runs entirely inside the extension on your machine. The recognized number is placed on your clipboard. That is the whole product.
The captured image exists only in memory, only for the moment of recognition, and is discarded when the picker closes. The recognized number goes to your clipboard and nowhere else. Neither ever leaves your computer: CertGrab contains no code that talks to a server, ours included.
activeTab — access the current page only when you invoke the picker, never in the background. scripting — draw the selection overlay on that page. clipboardWrite — place the recognized number on your clipboard. offscreen — run the OCR engine in an offscreen document.
If CertGrab's behavior ever changes in a way that affects this policy, we will update this page and the extension's listing before shipping the change. Questions: support@slabstickr.com.
