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
capi.grammarly.com is a subdomain of grammarly.com, the same organization as the app bundle id com.grammarly.keyboard, so it is most likely a first-party backend endpoint (the 'capi' label suggests a client API, though I cannot confirm its exact function). The app's label declares no collection at all, which is notable, but the observed contact alone does not tell us what data (if any) is transmitted, so I cannot substantiate an undisclosed data flow.
OpenAI — first-party
The domain is a grammarly.com subdomain and most likely operated by the app's own service. Because the app declares no data collection or sharing, this observed app-service contact appears undisclosed.
Google Gemini — first-party
The domain capi.grammarly.com belongs to Grammarly, making this a first-party service endpoint for the Grammarly Keyboard app. Contacting a first-party backend API does not inherently indicate undisclosed data collection or third-party tracking.
