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
apigateway.americanexpress.com is a subdomain of americanexpress.com, the same organization that publishes the Amex app (bundle ID com.americanexpress.amexservice), and the name suggests a first-party API gateway backend. First-party backend communication for account and payment data is consistent with the app's declared collection of payment info, financial info, and identifiers, so nothing here implies an undeclared data flow.
OpenAI — first-party
The domain is under americanexpress.com and appears to be an American Express API gateway, making it most likely first-party service infrastructure. The app's label declares extensive collection categories that could cover data sent to this endpoint, so undisclosed collection cannot be established from the provided information.
Google Gemini — first-party
The domain apigateway.americanexpress.com is a first-party API endpoint owned and operated by American Express for core application functionality. Standard communication with a first-party backend does not represent an undisclosed third-party data flow.
