Grammarly and your company’s data
By David Michaelson, MS Last checked October 23, 2026
The short answer
Team accounts bought through Grammarly’s Sales team start with “Product Improvement and Training” off; on Free, Premium, single-user Pro, and team accounts bought on the website, it starts on, so your writing may train Grammarly’s models until you turn it off.
Safer setup: Buy team accounts through Grammarly’s Sales team, where training starts off, or have your admin turn off “Product Improvement and Training” for the whole organization.
