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
mzstatic.com is Apple's own static media/asset host (App Store artwork, screenshots, icons), so for Apple's own App Store client this is first-party CDN content delivery rather than third-party tracking. Fetching static assets does not by itself imply a data collection or sharing flow beyond what a store client inherently requires, so nothing here contradicts the empty label.
OpenAI — cdn
The mzstatic hostname appears consistent with static asset or CDN delivery. This contact alone does not establish a data flow that conflicts with the app's empty privacy label.
Google Gemini — cdn
is4-ssl.mzstatic.com is owned by Apple and functions as a content delivery network used to serve static media assets. Contacting a CDN for essential app content delivery does not inherently indicate undisclosed data collection.
