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. 2 of 3 models answered, overall confidence low — classification split: openai=unknown, gemini=analytics · undisclosed split: openai=false, gemini=true · no answer from anthropic (parse). A human reviewed this domain's claims before anything here published.
OpenAI — unknown
The domain is ambiguous from the provided information, and no owner or purpose is supplied. Although the app declares nothing, the contact alone does not establish a data flow that its label fails to cover.
Google Gemini — analytics
fscdn.eppo.cloud is operated by Eppo, a feature flagging and experimentation platform used for analytics and A/B testing. Because the app declares collecting no data in its privacy label, transmitting telemetry or interaction data to a third-party analytics provider appears undisclosed.
