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=advertising, gemini=first-party. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
advertising.walmart.com is a subdomain of walmart.com, the app publisher's own domain, so this is first-party infrastructure (apparently serving an ad/retail-media function such as Walmart Connect) rather than a third-party tracker; I cannot verify ownership beyond the shared registrable domain. The label already declares collecting Device or other IDs, App interactions, and User IDs and sharing Device IDs, Email, and User IDs, so this contact implies no data flow outside the declared label.
OpenAI — advertising
The advertising.walmart.com subdomain strongly suggests Walmart's advertising operation. The app declares collecting and sharing identifiers, email addresses, and user IDs, so this contact does not clearly imply an undeclared data flow.
Google Gemini — first-party
The domain advertising.walmart.com is a first-party subdomain belonging to Walmart for its internal advertising and retail media network. Because it is operated by the app's own publisher and extensive data collection is declared, this contact does not appear undisclosed.
