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 — cdn
cdn.auth0.com is the asset-delivery/CDN hostname for Auth0's hosted login components (Auth0 is an identity provider now part of Okta), and ChatGPT's sign-in flow is consistent with fetching such static login assets rather than sending analytics or ad data. Fetching CDN-hosted login resources is authentication infrastructure and implies no data flow beyond the account/contact data the label already declares, so nothing here appears undisclosed.
OpenAI — cdn
cdn.auth0.com appears to serve Auth0 authentication-related web assets via a CDN. The provided information does not establish a data flow beyond the app's declared privacy label.
Google Gemini — cdn
cdn.auth0.com is Auth0's content delivery network used to host authentication SDKs and resources. This functional domain contact supports account sign-in/authentication, which aligns with the app's declared collection of user identity data.
