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
customer-api.delta.com is a subdomain of delta.com, the app publisher's own domain (Fly Delta, bundle id com.delta.iphone.ver1), so this is first-party backend/API traffic rather than a third-party tracker. The app's label already declares collecting identifiers, contact, payment and app-interaction data, which covers a first-party customer API call.
OpenAI — first-party
The domain is a delta.com subdomain and is most likely operated by Delta for its own customer API. The app declares several relevant categories of collection and sharing, so the contact alone does not establish an undisclosed data flow.
Google Gemini — first-party
The domain customer-api.delta.com belongs to Delta Air Lines and serves as a first-party API endpoint for the Fly Delta app. Standard interaction with a first-party domain for app operations does not indicate undisclosed third-party data sharing or tracking.
