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
securepubads.g.doubleclick.net is Google's Ad Manager / publisher ad-serving endpoint (Google LLC), used to request and render ads rather than for first-party app functionality. The app's label declares sharing Device or other IDs, which plausibly covers the identifier flow implied by an ad-serving request, so this contact does not appear undisclosed from the data given.
OpenAI — advertising
securepubads.g.doubleclick.net is a Google DoubleClick advertising domain. The app declares sharing Device or other IDs, which can cover an advertising-related contact; the provided data does not establish an additional undeclared flow.
Google Gemini — advertising
securepubads.g.doubleclick.net is part of Google's DoubleClick ad-serving platform. The contact appears disclosed as the app explicitly declares sharing device or other IDs.
