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
graph-fallback.facebook.com is a Meta-operated hostname in the facebook.com domain, apparently a fallback endpoint for the Graph API, so contact from Facebook's own app is first-party backend traffic. The app's label declares extensive collection including device IDs and app interactions, so this contact implies no data flow beyond what is declared.
OpenAI — first-party
The domain is a facebook.com subdomain contacted by Facebook, so it most likely provides first-party Facebook/Meta services. The label declares extensive collection and sharing categories, so this contact alone does not imply an uncovered data flow.
Google Gemini — first-party
The domain graph-fallback.facebook.com is owned by Meta, making it a first-party endpoint for the Facebook app. First-party functional API traffic does not indicate undisclosed data collection.
