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 — undisclosed split: anthropic=false, openai=true, gemini=false. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
attest.perplexity.ai is a subdomain of perplexity.ai, the app publisher's own domain (bundle ID ai.perplexity.app), so this is first-party infrastructure; the 'attest' hostname suggests a device/app attestation or integrity-check endpoint, though I cannot confirm its exact function. Because I cannot determine from the data given what payload is sent, I do not mark it undisclosed — but the 'nothing declared' label paired with any live first-party server contact is worth human verification, since attestation flows can carry device identifiers.
OpenAI — first-party
The domain is a subdomain of perplexity.ai and most likely serves Perplexity's own attestation or app-integrity function. The app declares no data collection or sharing, so this measured network contact appears undisclosed.
Google Gemini — first-party
The domain attest.perplexity.ai is a subdomain of the app developer's primary service (Perplexity) and represents a first-party operational endpoint used for app or device attestation. As a necessary first-party request, it does not imply undisclosed third-party data tracking or sharing.
