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. 2 of 3 models answered, overall confidence high — no answer from gemini (parse). A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
optum.com is the domain of Optum, a health services/benefits company (part of UnitedHealth Group), and the 'obapi-api' host appears to be a service API endpoint rather than a known tracking, analytics, ad, or CDN host — I cannot determine its specific function, and I do not have owner attribution for this subdomain from Apple. For a system wallet/pass app, such a contact is plausibly user-initiated (e.g., provisioning a health or benefits card issued by that provider), so from the information given I cannot conclude the flow falls outside the app's label.
OpenAI — unknown
The provided information does not establish what service obapi-api.optum.com performs or what data is transmitted. With no evidence that the contact implies a data flow, undisclosed status cannot be determined.
