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 — first-party
The hostname embeds the app's own bundle id and the 'weblab' path segment associated with Amazon's internal A/B testing/feature-flag infrastructure on a2z.com, which is generally understood to be an Amazon-operated domain, making this first-party experimentation/config traffic rather than a third-party tracker. Any resulting data flow (app interactions, diagnostics, device IDs) is already covered by the app's declared collection categories, so nothing here appears undisclosed.
OpenAI — first-party
The domain is under a2z.com and includes amazonbusiness, strongly indicating Amazon infrastructure used for the Amazon Business app. The app's privacy label declares extensive collection and sharing categories that would cover typical app telemetry or experimentation contacts.
Google Gemini — first-party
The domain a2z.com is owned by Amazon and used for internal infrastructure such as WebLab feature experimentation, making this a first-party contact aligned with the app's declared data collection.
