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 — first-party
claude.ai is the primary service domain matching the app's own name and bundle identifier (com.anthropic.claude), so this is first-party backend communication rather than a third-party tracker. The app's label already declares collecting user content, identifiers, and diagnostics, which covers a data flow to its own service.
OpenAI — first-party
The contacted domain, claude.ai, appears to be the app's own service domain based on the app name and bundle identity. The broad declared collection and sharing categories cover likely app-service communications, so this contact does not by itself imply an undisclosed flow.
Google Gemini — first-party
The domain claude.ai is the primary first-party service domain for Anthropic's Claude app. This contact represents standard first-party app functionality and is not undisclosed.
