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 medium — classification split: anthropic=unknown, openai=unknown, gemini=analytics. A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
payfone.com is associated with Payfone (later branded Prove), a mobile phone/device identity verification and anti-fraud vendor rather than an ad, analytics, or CDN network, so none of the offered categories fit cleanly; a 'device' subdomain endpoint is consistent with device/phone identity signaling for login or step-up authentication. The app already declares collecting Device or other IDs and Phone number, and Apple's labels treat data used solely for fraud prevention and security as optional to disclose, so nothing here clearly exceeds the declared label.
OpenAI — unknown
The provided data does not establish what service device.payfone.com provides or what data is transmitted. Chase declares collection of device identifiers, phone number, financial information, and app activity, so an undisclosed flow cannot be determined from this contact alone.
Google Gemini — analytics
Payfone (now Prove Identity) provides mobile identity verification and device intelligence services. The app's privacy label explicitly declares collecting 'Device or other IDs' and 'Phone number', covering the data flows associated with this service.
