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
gsp51-ssl.ls.apple.com is an Apple-operated location services (ls.apple.com) endpoint, and com.apple.mobileslideshow is Apple's own Photos app, so this is a first-party contact by the same vendor. Apple's built-in system apps typically do not carry App Store privacy labels, so the absence of declarations here is not evidence of an undisclosed flow.
OpenAI — first-party
The ls.apple.com domain is an Apple-controlled namespace and is likely used for Apple service infrastructure. No evidence provided establishes a data flow beyond the app's label, so undisclosed status cannot be determined.
Google Gemini — first-party
The domain gsp51-ssl.ls.apple.com is owned by Apple and hosts location/geo-services infrastructure for first-party system apps like Photos. Because this is standard first-party functional traffic, it does not indicate an undisclosed third-party data flow.
