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 — undisclosed split: anthropic=false, openai=true, gemini=false. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
bunsen.yelp.com is a subdomain of yelp.com, the same publisher as the app (com.yelp.yelpiphone), so it is a first-party endpoint; I do not know the specific function of the 'bunsen' host (it could be internal event logging, but I cannot confirm that from the data given). The declaration fields read '(nothing declared)', which may reflect missing input rather than a genuinely empty privacy label, and a first-party connection alone does not establish a data flow outside the label, so undisclosed is set to false pending human verification of the actual App Store label.
OpenAI — first-party
The contacted domain is a yelp.com subdomain and therefore appears first-party to the Yelp app. Because the app declares no collection or sharing, this observed app-domain contact appears undisclosed.
Google Gemini — first-party
The contacted domain bunsen.yelp.com is a subdomain of Yelp's primary domain, making it first-party to the app. A first-party endpoint contact alone does not demonstrate an undisclosed data flow without details on the payload.
