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 medium — classification split: anthropic=first-party, openai=cdn, gemini=first-party. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
assets.claude.ai is a subdomain of claude.ai, the app publisher's own domain (Anthropic, matching bundle id com.anthropic.claude), and the 'assets' hostname suggests first-party static asset or resource delivery; whether a third-party CDN fronts it cannot be determined from the data given. Contact with the app's own service backend is inherent to its declared functionality and data collection, so nothing here implies a flow outside the declared label.
OpenAI — cdn
The assets.claude.ai hostname appears to be an asset-serving subdomain for Claude, but ownership and its exact function are not independently provided. A contact to an app asset domain alone does not imply a data flow beyond the broad categories declared in the privacy label.
Google Gemini — first-party
The domain assets.claude.ai is a first-party subdomain owned by the app developer (Anthropic) used to serve static assets and app functionality. Because it is first-party operational traffic, it does not represent undisclosed tracking or third-party sharing.
