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
auth.openai.com is an OpenAI-owned subdomain serving the login/authentication flow for OpenAI's own app (bundle id com.openai.chat), so it is first-party infrastructure; note that such branded auth subdomains are sometimes fronted by a third-party identity provider, which I cannot confirm from the data given. Account-related data (name, email address) is already declared as collected, so this contact implies no flow outside the label.
OpenAI — first-party
auth.openai.com appears to be an OpenAI authentication endpoint associated with the app's service. The provided privacy label includes account/contact information and app interaction data that could cover authentication-related processing.
Google Gemini — first-party
auth.openai.com is a first-party subdomain owned by OpenAI used for authentication services, aligning with standard first-party functionality and the app's disclosed user account data collection.
