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
sdk-api-v1.singular.net is the SDK ingestion endpoint for Singular (Singular Labs, Inc.), a mobile marketing measurement and ad-attribution platform, so the contact fits advertising/attribution rather than first-party or CDN traffic. The app's label already declares sharing Device or other IDs, User IDs, and App interactions, which covers the data an attribution SDK typically transmits, so nothing here clearly exceeds the declared label.
OpenAI — analytics
sdk-api-v1.singular.net is owned by Singular Labs, Inc., a mobile attribution and analytics provider. The app declares collection and sharing of Device or other IDs, App interactions, User IDs, and location, which cover the likely data flow.
Google Gemini — tracker
Singular Labs is a mobile marketing attribution and analytics tracking platform. This contact appears disclosed because the app explicitly declares collecting and sharing Device or other IDs and App interactions.
