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=tracker, openai=analytics, gemini=analytics. A human reviewed this domain's claims before anything here published.
Anthropic Claude — tracker
appsflyersdk.com is the SDK endpoint domain for AppsFlyer, a mobile attribution and marketing-analytics provider, and the random-looking subdomain is consistent with AppsFlyer's per-app dedicated launch/attribution endpoints; attribution SDKs are best treated as third-party trackers rather than pure first-party analytics. The app's label declares collecting and sharing 'Device or other IDs' (plus app interactions and user IDs), which plausibly covers an attribution call, so nothing here clearly exceeds the declared label.
OpenAI — analytics
The appsflyersdk.com domain indicates an AppsFlyer SDK endpoint, which is commonly used for mobile attribution and analytics. The label declares collection of app interactions and device identifiers and sharing of device or other IDs, so the contact is not clearly outside the declared data flows.
Google Gemini — analytics
The domain belongs to AppsFlyer, a mobile attribution and analytics platform. The app explicitly declares collecting and sharing Device or other IDs and tracking app interaction data, covering this SDK traffic.
