RelevantKnowledge (RK) is a separate optional research offer from TMRG, a Comscore company. It collects browsing and app activity in the background. We may be paid if you join. Scan to PDF Converter works without RK. Participation is decided only in the visible official Agree / Decline screen. Accepting this application license does not accept RK research. RK is managed and uninstalled separately in Windows Settings > Apps.
