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 — analytics
The subdomain 'metricreceiver' on cellrebel.com is consistent with a third-party mobile network performance measurement/telemetry endpoint (CellRebel markets such an SDK, though I cannot verify domain ownership from the data provided), so it is best classified as analytics rather than ad serving. Since the app's label as given declares no collection or sharing at all, an outbound metrics-receiving endpoint implies a data flow the label does not cover.
OpenAI — analytics
The hostname "metricreceiver" indicates a metrics/telemetry collection endpoint, likely used for analytics or network-performance measurement. The app declares no collection or sharing, so this apparent analytics contact is not covered by its label.
Google Gemini — analytics
CellRebel is a network performance analytics platform owned by Ookla, and the metricreceiver subdomain indicates telemetry collection. Because the app declares no data collection or sharing, this contact appears undisclosed.
