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
mads.amazon-adsystem.com is an ad-serving endpoint on Amazon's amazon-adsystem.com advertising domain (owner listed as Amazon Technologies, Inc.), and mobile ad requests to it typically carry device/advertising identifiers. The app's store label declares no data collection or sharing at all, so this ad-network contact implies a data flow the label does not cover.
OpenAI — advertising
mads.amazon-adsystem.com is an Amazon Ads domain and most likely supports advertising-related functions. The app declares no data collection or sharing, so this advertising contact appears undisclosed.
Google Gemini — advertising
The domain mads.amazon-adsystem.com is operated by Amazon for mobile advertising services. Contacting an ad network endpoint appears undisclosed because the app's privacy label declares no data collection or sharing.
