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 — advertising
amazon-adsystem.com is Amazon's ad-serving/Amazon Publisher Services domain, and the 's.' host is used for ad requests and bidding, which typically involve device or advertising identifiers. The app's label declares no collection or sharing at all, so an advertising exchange contact implies a data flow the label does not cover; if the 'nothing declared' field actually reflects missing label data rather than a 'No Data Collected' declaration, this judgment should be revisited.
OpenAI — advertising
s.amazon-adsystem.com is Amazon's advertising system domain. The app declares no data collection or sharing, so this advertising-related contact appears undisclosed.
Google Gemini — advertising
s.amazon-adsystem.com is an ad-serving and tracking domain operated by Amazon Advertising. Because the app declares no data collection or sharing in its store privacy label, this contact appears undisclosed.
