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=first-party, openai=unknown, gemini=first-party. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
trk.mgs.opentable.com is a subdomain of opentable.com, the app publisher's own domain, so it is first-party infrastructure; the 'trk'/'mgs' labels suggest a self-hosted link/message click-tracking endpoint rather than a third-party network, though I cannot verify its exact function from the data given. Any identifiers or interaction events sent there fall within the app's declared collection of Device or other IDs, User IDs, and App interactions.
OpenAI — unknown
The opentable.com subdomain suggests a first-party service, but the 'trk' hostname alone does not establish whether it is tracking, analytics, or another function. The declared label already covers device IDs and app interactions, so an undisclosed flow cannot be determined from the provided information.
Google Gemini — first-party
The contacted domain trk.mgs.opentable.com is a subdomain of opentable.com, matching the app developer, making it a first-party endpoint. Communication with the app's own domain is consistent with first-party operations and declared data practices.
