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 low — classification split: anthropic=advertising, openai=analytics, gemini=tracker. A human reviewed this domain's claims before anything here published.
Anthropic Claude — advertising
skan.singular.net is an endpoint of Singular, a mobile measurement/attribution vendor, and the 'skan' hostname indicates SKAdNetwork ad-attribution conversion handling, so the contact is ad-attribution infrastructure rather than app-owned or CDN infrastructure. Because the app's label declares no data collection or sharing at all, a third-party attribution contact implies at least device/usage or identifier data going to an ad-tech vendor that the label does not cover; note that if the actual flow were limited to Apple-mediated SKAdNetwork postbacks, Apple may not require its declaration, so this judgment rests on the SDK-side contact observed here.
OpenAI — analytics
skan.singular.net is associated with Singular's mobile attribution and SKAdNetwork measurement services. The app declares no collection or sharing, so this analytics/attribution contact appears not covered by the label.
Google Gemini — tracker
skan.singular.net is operated by Singular, a mobile measurement partner used for ad attribution and tracking. Because the app declares no data collection or sharing in its privacy label, this third-party contact appears undisclosed.
