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=unknown, gemini=first-party. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
aliyun.com is Alibaba Cloud, the same corporate group as AliExpress's publisher (Alibaba), and the 'ntp' hostname is consistent with a Network Time Protocol time-sync endpoint rather than a data-collection or ad endpoint; I cannot verify ownership from Apple's label data here, only from the domain's well-known association with Alibaba Cloud. Time synchronization implies no user-data flow beyond the device's own network connection, so nothing appears outside the declared label.
OpenAI — unknown
ntp.aliyun.com appears to be an NTP/time-synchronization endpoint, but ownership and the specific data transmitted are not provided. A time-sync contact alone does not establish a data flow beyond the app's declared categories.
Google Gemini — first-party
ntp.aliyun.com is an Alibaba Cloud Network Time Protocol (NTP) server used for clock synchronization, which represents first-party network infrastructure.
