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. 2 of 3 models answered, overall confidence high — no answer from gemini (parse). A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
The "speedtest." hostname pattern strongly suggests a network measurement endpoint, and Speedtest apps connect to a large pool of third-party-hosted test servers (often ISPs/carriers) as core functionality; I do not know with certainty who owns mtc4me.com, so I will not name an operator. Because this looks like a functional throughput-test endpoint rather than a tracking, analytics, or ad service, the contact does not by itself imply a data flow beyond the app's stated purpose, and the evidence given is insufficient to call it undisclosed.
OpenAI — unknown
The ownership and function of speedtest.mtc4me.com are not provided, so its role is ambiguous. With no evidence of what data the contact transmits, an undisclosed data flow cannot be determined.
