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 low — classification split: anthropic=first-party, openai=unknown · no answer from gemini (parse). A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
online.americanexpress.com is American Express Company's own consumer servicing domain, and Apple Wallet (com.apple.Passbook) contacts card-issuer endpoints as part of user-initiated pass/card provisioning and updates rather than for tracking or ads; note it is first-party to the card issuer, not to Apple, so a stricter developer-centric definition would treat it as a functional third-party service. Wallet is a preinstalled system app with no App Store privacy label, so the absence of declared collection/sharing is not evidence that this flow is undisclosed.
OpenAI — unknown
The domain appears associated with American Express but no ownership or contact-purpose evidence is provided, so its role is ambiguous. With no evidence of what data was transmitted, an undisclosed data flow cannot be determined.
