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
flag.lab.amplitude.com is an Amplitude domain; the 'lab'/'flag' subdomain corresponds to Amplitude Experiment, its feature-flag and A/B testing service, which is part of its product analytics platform. The app's label already declares collecting and sharing App interactions, User IDs, Device or other IDs, and diagnostics data, which covers this type of analytics flow, so nothing here appears outside the declared label.
OpenAI — analytics
