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
icloud.com is Apple's own service domain, and the shard-style hostname (p167-...) is consistent with Apple's iCloud partition endpoints, so Apple Mail contacting it looks like first-party mail/account functionality rather than a third-party tracker; I do not know specifically what the 'mcc' subdomain component serves. A first-party service call needed for the app's core function does not by itself imply a data flow outside the declared label, so nothing here appears undisclosed.
OpenAI — first-party
The icloud.com domain is associated with Apple's iCloud service and is plausibly first-party infrastructure for Apple Mail. No evidence is provided about a data flow beyond the contact itself, so undisclosed status cannot be determined.
Google Gemini — first-party
The domain icloud.com is owned by Apple and serves as first-party backend infrastructure for Apple Mail (com.apple.mobilemail). Operational communication with first-party servers for core functionality does not indicate undisclosed data collection or sharing.
