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. 2 of 3 models answered, overall confidence low — classification split: anthropic=first-party, openai=unknown · no answer from gemini (parse). A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
ucweb.com belongs to UCWeb (the UC Browser developer), which is part of Alibaba Group, so for an Alibaba-published app this looks like corporate-affiliate first-party infrastructure rather than an independent tracker; the specific role of the 'px-intl' subdomain (possibly push or performance telemetry) is not something I can verify. Any device ID or diagnostic data sent there appears covered by the app's declared collection of Device or other IDs, app interactions, diagnostics, and performance data, so nothing here clearly exceeds the label.
OpenAI — unknown
The domain ownership and purpose are not provided, and the domain name alone is insufficient to reliably classify it. The app declares extensive collection categories, so this contact cannot be shown to imply an undeclared data flow from the given information.
