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 — first-party
googleapis.com is Google's own API domain, and the '-pa' suffix is a Google internal/private API endpoint pattern; for Google's own Gmail app this is a first-party backend call, and the 'peoplestack' name suggests a people/contacts service consistent with the app's declared collection of Contacts, Name, and Email address. I do not have independent documentation of what peoplestack-pa specifically does, so the exact function is uncertain, but nothing here implies a flow outside the declared label.
OpenAI — first-party
The domain is a googleapis.com endpoint and is most likely operated by Google, the Gmail app's provider. Gmail's label declares broad collection including Contacts and other account data, so this contact does not clearly imply an undeclared data flow.
Google Gemini — first-party
peoplestack-pa.googleapis.com is a Google-owned API endpoint for managing contacts and profile services, making it a first-party endpoint for the Gmail app. The app explicitly declares collecting contacts and user profile data, so this contact is disclosed.
