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
alicdn.com is Alibaba Group's own content delivery domain (sc04 is one of its image/static asset hosts), so this is first-party CDN infrastructure for the Alibaba.com app rather than a third-party tracker. Serving app images and static content does not imply a data flow beyond the app's declared collection, so nothing appears undisclosed.
OpenAI — cdn
The alicdn.com domain name indicates Alibaba's content-delivery infrastructure, and the sc04 subdomain is consistent with serving static content. A CDN contact alone does not establish a data flow absent from the app's broad declared collection categories.
Google Gemini — cdn
sc04.alicdn.com is part of Alibaba Group's content delivery network (AliCDN) used to host and deliver static assets for its applications. As first-party infrastructure delivering app content, this contact does not represent undisclosed tracking or third-party data collection.
