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
www.booking.com is the app's own primary domain, matching the bundle ID com.booking.BookingApp, so this is first-party backend/web contact. The app's label already declares extensive collection (identifiers, contact info, payment info, app interactions), which covers a first-party data flow.
OpenAI — first-party
The contacted domain is Booking.com's own www.booking.com domain and is consistent with core app functionality. The privacy label declares broad collection and sharing categories that cover likely data flows from this contact.
Google Gemini — first-party
The domain www.booking.com belongs directly to the app developer (Booking.com) and serves as its primary first-party service endpoint. First-party communication for core app functionality is expected and covered by the declared privacy label.
