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
amplitude.com is the domain of Amplitude, a product analytics vendor; the 'api.lab' subdomain is consistent with its experimentation/feature-flag service, which is analytics rather than ad-targeting. The app's label declares collecting and sharing App interactions, User IDs, Device or other IDs, and diagnostics/performance data with third parties, which plausibly covers this flow.
OpenAI — analytics
api.lab.amplitude.com is an Amplitude endpoint commonly used for product analytics. The app's label declares collection and sharing of app interactions, device IDs, user IDs, diagnostics, and other relevant data categories, so this contact is not clearly undisclosed.
Google Gemini — analytics
