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=first-party, openai=unknown, gemini=first-party. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
attester.gateway.icloud.com is Apple's own iCloud/App Attest attestation endpoint (DeviceCheck/App Attest anti-fraud device attestation), i.e., OS-level platform infrastructure rather than a third-party data recipient; it may not even be app-attributable traffic. Because Apple's platform services are outside the scope of a developer's privacy label and no user data collection is implied, this contact does not indicate an undisclosed flow.
OpenAI — unknown
The domain is under icloud.com, but no ownership or purpose evidence is provided here, so its role is ambiguous. With no evidence that this contact transmits app data beyond the label, it cannot be determined to be undisclosed.
Google Gemini — first-party
attester.gateway.icloud.com is an Apple-owned domain used by iOS for App Attest and device integrity verification. As standard platform security infrastructure, this contact does not indicate an undisclosed privacy violation.
