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 — first-party
aliyuncs.com is the domain used by Alibaba Cloud (Aliyun), the cloud arm of Alibaba Group, which also publishes AliExpress, so this looks like first-party/corporate-affiliate infrastructure rather than a third-party tracker; the 'cloud-config-service.rtc' hostname suggests remote configuration for a real-time communication component, though I cannot confirm its exact function from the data given. Any identifiers or diagnostics sent to a first-party config endpoint appear covered by the app's declared collection of Device or other IDs, User IDs, and Diagnostics, so nothing here implies an undeclared data flow.
OpenAI — first-party
The aliyuncs.com domain is associated with Alibaba Cloud infrastructure, and this RTC cloud-configuration endpoint appears plausibly used by AliExpress as an Alibaba-operated service. The domain alone does not establish a data flow beyond the app's declared collection categories.
Google Gemini — first-party
The domain belongs to Alibaba Cloud (Alibaba Group), making it first-party infrastructure for the AliExpress app. Standard cloud configuration requests for first-party operational functionality do not indicate an undisclosed third-party data flow.
