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
in.grammarly.com is a subdomain of grammarly.com, the same organization as the app bundle com.grammarly.keyboard, so it is a first-party endpoint; the "in." prefix is often used for ingest/telemetry, but I cannot confirm its function from the data given. Because the label declares no collection at all, a first-party server contact alone does not prove a data flow requiring disclosure (Apple permits omitting data processed only on-device or not retained), so this is marked not undisclosed pending payload inspection by a reviewer.
OpenAI — first-party
The domain is a Grammarly subdomain and most likely serves the app's own backend. The app declares no data collection or sharing, so this observed app-to-Grammarly contact appears undisclosed.
Google Gemini — first-party
The domain in.grammarly.com shares ownership with the app developer (Grammarly), making it a first-party endpoint. Contact with a first-party domain alone does not establish an undisclosed data flow.
