The * stands for a machine-generated segment — this service mints a fresh hostname per device or install (a UUID or random blob), so the individual hostnames carry no information the family doesn't. We group them into one claim per app: corroboration is counted across all member hostnames, and every claim below cleared the same two gates as everything else on this site — separate accepted donations and human review.

A hostname family · classified as unknown
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 low — classification split: openai=tracker, gemini=analytics · no answer from anthropic (parse). A human reviewed this domain's claims before anything here published.
OpenAI — tracker
The marketingcloudapis.com device endpoint appears consistent with a mobile marketing or device-registration service. Because the app declares no data collection or sharing, this contact appears undisclosed.
Google Gemini — analytics
The domain marketingcloudapis.com is operated by Salesforce Marketing Cloud for mobile push services and engagement analytics. Because the app declares no data collection or sharing, this communication appears undisclosed.
