This page aggregates measured, corroborated evidence: donors' iPhones recorded apps contacting this domain, every claim below was reported by separate accepted donations and published under a human verdict (later rows for an approved app inherit its verdict). A contact is a measurement, not an accusation — it does not show what data was sent.

What our research panel found AI-drafted · human-reviewed
We ask several independent AI models the same question and publish their answers separately — cross-vendor agreement is evidence against fabrication, and disagreement is worth seeing. 3 of 3 models answered, overall confidence high. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
clients4.google.com is a Google-operated endpoint used by Google client applications, so for Google Maps (com.google.Maps) it is first-party infrastructure rather than a third-party tracker. The app's label already declares broad collection of device IDs, app interactions, location and diagnostics, which covers a first-party service call; the exact purpose of this specific endpoint is not determinable from the data given.
OpenAI — first-party
clients4.google.com is a Google-owned domain used by Google services and is most likely first-party for Google Maps. The app’s privacy label declares broad categories of collection, so this contact alone does not imply an undeclared data flow.
Google Gemini — first-party
clients4.google.com is an internal infrastructure domain owned by Google, the developer of Google Maps, making this a first-party contact. The interaction is consistent with the app's extensive set of declared data collection types.
