UTMs / click IDs in cookies or web storage

This page explains what this scan check measures. It is not legal advice or a compliance verdict.

What this check is

This check looks for UTM or click-ID values stored in cookies or web storage during the visit.

HandL UTM Grabber and similar WordPress tools write first-party keys so values survive navigation.

Without durable storage, refresh and multi-page flows lose context. This is an attribution durability check, not a privacy-law verdict.

Install or fix first-party capture, re-scan, and confirm values appear in storage when expected.
