p30-mcc.icloud.com

classified as first-party · 2

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 domain, and the 'p30-' prefix is characteristic of Apple's sharded iCloud service hosts; for Apple Mail this looks like first-party account/mail sync infrastructure rather than a third-party tracker. The declared-label fields are empty (Apple's built-in apps are not distributed with third-party-style App Store labels in this data), so no undisclosed third-party data flow can be established from what is given.

OpenAI — first-party

The icloud.com domain is plausibly an Apple first-party service endpoint used by Apple Mail. No evidence is provided about the specific data transmitted, so an undisclosed data flow cannot be determined.

Google Gemini — first-party

The domain p30-mcc.icloud.com is owned by Apple and provides backend infrastructure for iCloud services. Contact by Apple's Mail app represents core first-party operational functionality rather than third-party tracking or undisclosed data collection.

Think something here is wrong?

Evidence and research improve when people push back. Tell us what to re-check — a misattributed domain, an outdated classification, a claim about your own app — and a human will review it. Responses can take up to 30 days.

If you leave an email it is encrypted at rest and opened only to answer you — never shared, never used for anything else. It is erased 30 days after we resolve this (or 180 days if it is still open) without you asking, and you can erase it sooner at any time; either way your correction stays, anonymously. Leave it blank and your request is fully anonymous from the start (we store no IP address either way).
