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=first-party, openai=analytics, gemini=first-party. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
firestore.googleapis.com is Google Cloud Firestore, a Google-operated backend-as-a-service database that apps use to store and sync their own data, so traffic here typically functions as first-party app backend rather than an advertising or analytics endpoint (note: the category schema fits imperfectly, since the domain is Google-owned infrastructure used on the developer's behalf). The contact is consistent with the app's declared collection of app interactions, user content, and messages, so nothing here shows a flow outside the label.
OpenAI — analytics
firestore.googleapis.com is a Google Firebase Firestore service endpoint, commonly used for app backend data storage and synchronization; the specific use is not identifiable from the domain alone. The declared label includes several relevant data categories, so this contact alone does not establish an undisclosed flow.
Google Gemini — first-party
Google Cloud Firestore (firestore.googleapis.com) is a cloud backend database service used for application data storage and functionality. Using first-party database infrastructure for app operations aligns with standard app operations and does not indicate an undisclosed data flow.
