Assessment

Free and Pro (personal): mediumBusiness and Enterprise: unrated

Reasoning: Everything a person types with the extension active passes to US servers, and the policy grants Grammarly use of that writing to improve its products. Third-party training is excluded and the DPF certification covers the transfer. The tool's reach is the issue: it reads whatever field it is enabled in, which in a browser includes internal systems. Business-plan training controls are documented on a separate page not yet verified here, so those plans are unrated.

Flags: GDPR Chapter V (US storage; DPF-certified) · Assessed 2026-09-16. The assessment is Unseen's; the terms above are the vendor's.
