01 — The problem

The problem

Legal/marketing teams often lack reproducible evidence of whether the banner appears, whether a "Reject" option exists, and which cookies drop before/after consent.

Who it is for

Any company with a web/mobile app subject to cookie/privacy regulation that wants independent evidence of how its consent banner behaves on a real device.

03 — What runs

What runs

  • The worker loads the URL on a real Android device and records banner presence/absence, visible options (including whether a "Reject" option exists), and cookies set before vs. after consent.
  • A run never issues a legal-compliance verdict — it records what was observed, which the client’s own legal team evaluates.

08 — Known limitations

Known limitations

  • Never certifies legal compliance — it is supporting evidence, not a legal opinion.
  • Scope: shows how the banner behaves for visitors outside the EU. It is not an audit of what EU visitors see, and banners that target EU visitors by location may not appear in these runs.
  • In internal testing we have already found real banners missing a "Reject" option that drop third-party cookies before consent — exactly the kind of gap this check exists to catch.
  • Runs from a real phone with a real SIM in the served corridor; today the browsing path is the phone's Wi-Fi (the site sees a local fixed-line ISP address, not a mobile-carrier address); the network path is recorded in every signed run.

Questions about this service

No. It produces independent evidence that can support your own compliance and audit work — it never replaces legal advice or independent certification.
