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 high. A human reviewed this domain's claims before anything here published.
Anthropic Claude — analytics
api.amplitude.com is the event-ingestion endpoint for Amplitude, a product analytics provider, so this is third-party behavioral analytics rather than an ad or CDN endpoint. The app's label declares both collecting and sharing App interactions, Device or other IDs, User IDs, and diagnostics, which covers the data flow this contact implies.
OpenAI — analytics
api.amplitude.com is identified as owned by Amplitude and is commonly used for product analytics. The app declares collection and sharing of app interactions, identifiers, and other relevant usage data, so this contact is covered by the label.
Google Gemini — analytics
api.amplitude.com is an analytics service provided by Amplitude. The app discloses collecting app interactions, device IDs, and performance data, so this network activity appears covered by its privacy label.
