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
mobile.facebook.com is a Facebook-operated domain contacted by Facebook's own app, so it is first-party infrastructure rather than a third-party tracker. The app's label already declares extensive first-party collection, so this contact implies no data flow beyond what is disclosed.
OpenAI — first-party
mobile.facebook.com is a Facebook-operated domain associated with the Facebook app. The app's label declares extensive collection and sharing categories, so this contact alone does not imply an undisclosed data flow.
Google Gemini — first-party
mobile.facebook.com is a first-party domain operated by Meta for the Facebook service. The contact is consistent with standard first-party app functionality and does not represent an undisclosed third-party data flow.
