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
platform-lookaside.fbsbx.com is a Meta (Facebook) content-delivery endpoint commonly hit during Facebook Login flows to fetch user profile images via the Graph API picture endpoint, rather than a dedicated ad or analytics beacon; I cannot verify ownership beyond the well-known fbsbx.com Facebook domain from the data given. The contact is consistent with the app's declared collection of Name, Email address, User IDs and Photos for social sign-in, so nothing here implies a flow outside the label.
OpenAI — cdn
platform-lookaside.fbsbx.com is commonly used as a Facebook-hosted content delivery domain. A CDN contact alone does not establish a data flow beyond the app's broad declared collection and sharing categories.
Google Gemini — cdn
platform-lookaside.fbsbx.com is a CDN domain operated by Meta/Facebook for serving platform media and static assets. Because the app explicitly declares collecting and sharing device and user identifiers, this contact does not appear to be undisclosed.
