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 domain is a subdomain of grammarly.com, the same publisher as the app bundle com.grammarly.keyboard, and the 'assets' hostname pattern suggests it serves the app's own static resources (possibly via a CDN); I cannot confirm the hosting provider. Fetching first-party assets does not by itself imply a data collection or sharing flow that a privacy label would need to declare, so this is not evidence of an undisclosed flow.
OpenAI — first-party
The domain is a Grammarly subdomain and most likely serves first-party app assets. With no evidence of what data was transmitted, the contact alone does not establish an undisclosed data flow.
Google Gemini — first-party
assets.grammarly.com is a first-party domain belonging to Grammarly used for serving static app resources. First-party functional network contact for asset delivery does not inherently imply undisclosed data collection.
