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
tpc.googlesyndication.com is a Google ad-serving/SafeFrame domain used to deliver ad creatives and related ad-request traffic (Google AdSense/Ad Manager infrastructure); although it functions partly as creative delivery, it is advertising infrastructure rather than a neutral CDN. Since the app's label declares no collection or sharing at all, an ad-serving contact implies at least device/IP-level data flow to a third-party advertising system that the label does not cover.
OpenAI — advertising
tpc.googlesyndication.com is a Google advertising-related domain commonly used for ad serving and measurement. The app declares no data collection or sharing, so this contact appears undisclosed.
Google Gemini — advertising
tpc.googlesyndication.com is a Google-owned domain used to serve third-party ad content. Because the app declares no data collection or sharing in its privacy label, contacting an ad-serving domain appears undisclosed.
