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
pndsn.com is, to my knowledge, the endpoint domain for PubNub's real-time messaging/data-stream network (ps. = subscribe/presence host), which apps like ride-hailing clients typically use for functional live trip and driver-status updates rather than tracking or ads; since the provided taxonomy has no 'third-party infrastructure/SDK backend' category and no owner was supplied by Apple, I prefer 'unknown' over forcing a fit. The plausible data in such a flow (device/user IDs, app interactions, precise location) is already covered by the app's declared sharing, so nothing here indicates an undisclosed flow.
OpenAI — unknown
The domain appears to be associated with a real-time messaging/service endpoint, but its specific function and data payload are not established by the provided evidence. The privacy label already declares several relevant identifiers, app interactions, location, and diagnostics, so an undisclosed flow cannot be determined.
Google Gemini — cdn
ps.pndsn.com is operated by PubNub, a real-time messaging and data streaming network used for app features like live location and dispatch tracking. This functional backend infrastructure contact is consistent with the app's declared data collection and sharing disclosures.
