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 medium — classification split: anthropic=unknown, openai=unknown, gemini=cdn. A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
clients3.google.com is a Google-operated endpoint used for several different purposes (most commonly captive-portal/connectivity checks such as /generate_204, but also other Google client services), so its role here is ambiguous without request-level detail. A bare connectivity or service check does not clearly imply a data flow beyond the app's declared diagnostics/device-ID collection, so I cannot call it undisclosed.
OpenAI — unknown
The domain is a Google domain, but the provided information does not establish the specific service or data flow involved. The app's label declares extensive collection and sharing, so this contact alone does not show an undisclosed flow.
Google Gemini — cdn
clients3.google.com is a Google infrastructure domain frequently used for system services, WebView requests, and connectivity testing. This operational traffic does not conflict with the app's declared privacy disclosures.
