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
pubads.g.doubleclick.net is Google's DoubleClick for Publishers / Google Ad Manager ad-serving endpoint, used to request and serve ads, which normally involves passing device, IP, and advertising-identifier data. Since the store label declares no collection or sharing at all, this ad-serving contact implies a data flow the label does not cover; a human reviewer should confirm the label snapshot is current before publishing.
OpenAI — advertising
pubads.g.doubleclick.net is a Google advertising domain used to serve and measure ads. The app declares no collection or sharing, so this advertising-related contact appears not covered by its privacy label.
Google Gemini — advertising
pubads.g.doubleclick.net is an ad-serving domain operated by Google. Because the app's privacy label declares no data collection or sharing, contacting an advertising service appears undisclosed.
