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
facebook.com is operated by Meta, the publisher of Messenger, and the 'chat-e2ee' subdomain appears to be a first-party messaging/chat endpoint for the app's core function rather than a third-party service. The app's own label already declares collecting in-app messages, user IDs and device IDs, so this contact implies no data flow beyond the declared label.
OpenAI — first-party
The facebook.com domain is consistent with Messenger's first-party service infrastructure, and the e2ee subdomain suggests end-to-end encrypted chat functionality. Messenger declares collection of messages and extensive related data categories, so this contact does not by itself imply an undeclared flow.
Google Gemini — first-party
The domain chat-e2ee.facebook.com is owned by Meta and serves core end-to-end encrypted chat functionality for the Messenger app, making it a first-party operational domain.
