Ad tracking (C3b)

localStorage attribution keys

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

What this check is

This check specifically inspects localStorage for attribution keys written during the session.

Some WordPress stacks prefer localStorage over cookies for UTMs; others never write either.

Missing keys means this mechanism did not store attribution in localStorage on this run. Another storage path might still exist.

Align the capture library with localStorage expectations, then re-scan.
