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 — cdn
muscache.com is widely known as Airbnb's own static asset/image delivery domain (the 'a0' host serves listing photos and other media), so this is a first-party CDN contact rather than a third-party tracker; I am relying on general knowledge of the domain rather than a provided ownership record. Fetching app-owned media assets does not imply a data flow beyond the app's declared collection, so nothing appears undisclosed.
OpenAI — cdn
The muscache.com domain is consistent with Airbnb's cache/content-delivery infrastructure. A CDN contact alone does not establish a data flow beyond Airbnb's extensive declared collection and sharing categories.
Google Gemini — cdn
muscache.com is a content delivery network domain owned and operated by Airbnb to serve static assets and images. As a first-party CDN supporting essential app functionality, this contact does not represent an undisclosed third-party data flow.
