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=advertising, openai=analytics, gemini=analytics. A human reviewed this domain's claims before anything here published.
Anthropic Claude — advertising
The 'skan-s2s' hostname on singular.net indicates a SKAdNetwork server-to-server postback endpoint operated by Singular, a mobile ad attribution/marketing-measurement vendor, so the contact is advertising-attribution infrastructure rather than content delivery or first-party Uber infrastructure (I have no Apple-provided owner attribution here). SKAdNetwork postbacks convey install/conversion-event signals that plausibly fall under the app's declared sharing of 'App interactions,' and the payload contents are not visible from this measurement, so I cannot establish an uncovered data flow.
OpenAI — analytics
The skan-s2s.singular.net endpoint appears to be a server-to-server SKAdNetwork attribution/measurement endpoint. Uber declares sharing App Interactions and In-app Search History, which can cover attribution-related interaction reporting.
Google Gemini — analytics
skan-s2s.singular.net is operated by Singular, a mobile attribution and marketing analytics platform. Because the app explicitly declares collecting device IDs and sharing app interactions, this contact does not clearly indicate an undisclosed data flow based on the provided declarations.
