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=analytics, openai=analytics, gemini=tracker. A human reviewed this domain's claims before anything here published.
Anthropic Claude — analytics
appsflyersdk.com is the SDK domain of AppsFlyer, a mobile attribution and marketing-measurement provider, and the 'cdn-settings' host appears to be an SDK remote-configuration endpoint rather than a pure content CDN; I would treat it as third-party attribution analytics. The app's label already declares collecting and sharing Device or other IDs and App interactions, which covers the data flow this contact implies, so it does not appear undisclosed on the information given.
OpenAI — analytics
The domain is an AppsFlyer SDK settings endpoint, which is commonly associated with mobile attribution and analytics configuration. The app declares collection and sharing of device identifiers and app interactions, so this contact does not by itself imply an undeclared data flow.
Google Gemini — tracker
The domain belongs to AppsFlyer, a mobile attribution and analytics SDK. The app's privacy label discloses collecting and sharing Device or other IDs and App interactions, covering this data flow.
