FAQ & Support

Is this legal? Tracking pixels are embedded in publicly visible HTML and JavaScript — scanning for them is the same as what any browser does when loading the page.

Known limitations: Pixels loaded inside iframes or via server-side tagging (sGTM) may not be detected. Client-side pixels are fully supported.
