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=unknown, openai=unknown, gemini=cdn. A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
gcs-us-00003.content-storage-upload.googleapis.com is a Google Cloud Storage resumable-upload endpoint on googleapis.com (Google LLC infrastructure), which is generic backend/storage plumbing usable by any developer rather than an identifiable tracking, analytics, or ad service; it would be first-party if the app is genuinely published by Google, but the record's bundle ID (com.apple.mobilephone) contradicts the app name (Phone by Google), so the publisher cannot be established. Because the declared label already covers uploads such as voice recordings, crash logs, and diagnostics, and the destination cannot be attributed to a third party from what is given, this contact is not shown to be undisclosed; the bundle/name mismatch should be resolved before publication.
OpenAI — unknown
The domain is under googleapis.com and appears consistent with a Google content-storage upload endpoint, but the provided data does not establish its specific function or what data was transmitted. The app declares several relevant collection categories, so an undisclosed flow cannot be determined from this contact alone.
Google Gemini — cdn
The domain gcs-us-00003.content-storage-upload.googleapis.com is part of Google Cloud Storage infrastructure used for hosting and uploading content. Because this is first-party infrastructure for a Google-developed app and the app declares extensive data collection for its features, this contact does not appear undisclosed.
