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 — cdn
gstatic.com is Google's static-asset hosting domain, so gz.gstatic.com is a Google-owned CDN endpoint contacted by Google's own app (first-party CDN); the specific purpose of the 'gz' subdomain is not something I can verify. Static resource fetching from the app's own publisher does not imply a data flow beyond the app's extensive declared collection, so this does not appear undisclosed.
OpenAI — cdn
gz.gstatic.com is a Google static-content domain commonly used to deliver application resources. The provided privacy label already declares extensive collection categories, and the contact alone does not establish an undeclared data flow.
Google Gemini — cdn
gz.gstatic.com is a Google-owned static content delivery network (CDN) domain used to serve app assets. As first-party infrastructure for a Google app, routine asset fetching does not imply an undisclosed data flow.
