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 — classification split: anthropic=first-party, openai=analytics, gemini=first-party · undisclosed split: anthropic=false, openai=true, gemini=false. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
gnar.grammarly.com is a subdomain of grammarly.com, the same registrable domain as the app's developer (com.grammarly.keyboard), so it is a first-party endpoint; I do not know what specific service the 'gnar' host provides (it could be app functionality, config, or telemetry) and cannot confirm from the given data that any data is transmitted. Because the purpose is ambiguous, I do not assert an undisclosed flow, though a human reviewer may want to note that the app declares no data collection or sharing at all, which is unusual for a keyboard, and verify the payload of this endpoint before publishing.
OpenAI — analytics
The gnar.grammarly.com hostname appears to be a Grammarly-operated analytics/telemetry endpoint. The app declares no collection or sharing, so this measured analytics contact appears not covered by its privacy label.
Google Gemini — first-party
The domain gnar.grammarly.com belongs to the app's developer, making it a first-party endpoint. Contacting a first-party domain does not inherently imply undisclosed data collection without evidence of transmitted personal data.
