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 medium — classification split: anthropic=cdn, openai=first-party, gemini=cdn. A human reviewed this domain's claims before anything here published.
Anthropic Claude — cdn
yt3.googleusercontent.com is Google's user-content/image-serving domain (commonly YouTube channel avatars and thumbnails), so for Google's own Search app it is a first-party CDN endpoint rather than a third-party tracker. Fetching images from a CDN does not by itself imply a data flow beyond the app's extensive declared collection, so nothing here appears undisclosed.
OpenAI — first-party
yt3.googleusercontent.com is a Google-owned content-hosting domain commonly used to serve YouTube profile imagery and other Google content. The Google app declares broad collection categories, and the domain contact alone does not establish an undeclared data flow.
Google Gemini — cdn
yt3.googleusercontent.com is a Google-operated content delivery network domain used to host YouTube channel avatars, profile images, and static assets. As a first-party asset domain for a Google application, this traffic represents standard content delivery rather than undisclosed third-party data collection.
