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.ampproject.org serves the AMP runtime/library and AMP cache assets (the AMP project is now under the OpenJS Foundation, with the CDN historically operated by Google); Gmail's 'AMP for Email' feature is a plausible functional reason for this contact, so it reads as content-delivery rather than tracking. No advertising or third-party analytics data flow is implied beyond what Gmail's own label already declares, and since Gmail is a Google app this is effectively same-corporate-family infrastructure.
OpenAI — cdn
cdn.ampproject.org appears to be an AMP content delivery domain. The provided label declares broad collection categories, and the domain contact alone does not establish an uncovered data flow.
Google Gemini — cdn
cdn.ampproject.org is Google's content delivery network for serving Accelerated Mobile Pages (AMP) web content. Serving app content via a CDN is standard infrastructure behavior and does not indicate undisclosed data collection or sharing.
