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
sas.pcms.apple.com is a subdomain of apple.com, the same publisher as com.apple.Maps, so this is first-party infrastructure; I do not know the specific function of the 'sas.pcms' host. The absence of declared collection/sharing here appears to reflect missing or unavailable label data for a preinstalled Apple app rather than evidence of an uncovered data flow, so undisclosed cannot be established from what is given.
OpenAI — unknown
The provided data does not identify the owner or function of sas.pcms.apple.com, so its role is ambiguous. With no evidence of what data was transmitted, an undisclosed data flow cannot be established from the label information alone.
Google Gemini — first-party
The contacted domain belongs to Apple, which is the developer of Apple Maps. First-party service requests do not imply undisclosed third-party data sharing.
