Proof Studies

A proof study is an evidence-backed examination of measurement behavior on a real site: what fired on the wire, what it means, and where external observation stops. Studies are published anonymized — the site’s address and its identifiers are withheld.

We do not publish customer reports. Your report is yours; a scan you run is not material for this page.

What a study contains

  • The observation, stated exactly as strongly as the evidence supports.
  • The request receipts behind it: the beacons on the wire, timestamped.
  • Independent verification, in a browser separate from our own scanner.
  • The boundary: what external observation cannot prove, and what access would.
  • A date. Measurement changes silently; a study is true as of when it was verified.
