Does Grammarly train on your data?
NoGrammarly, Inc. · Writing
By default it can. On the consumer tier Grammarly uses your inputs to improve models unless you opt out. Its business tier typically does not.
What we checked
This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.
- Default data training
- Opt-out required
- Grammarly does not let LLM providers train on user content, but uses aggregated, de-identified samples for product improvement and training unless the user opts out via account controls.
- Business-tier training
- No by default
- Grammarly Business/Enterprise content is not used to train models and EU/UK user content is explicitly excluded from model training.
- Training control
- Confirmed
- Grammarly, Inc. documents a training control. Confirm whether it is enabled centrally or must be set by each user.
Practical risk: On free/Premium consumer tiers Grammarly uses de-identified content for product improvement/training unless you opt out, and HIPAA coverage requires an Enterprise BAA (not available on Free/Premium/Business).
How to make a decision
Check the precise account tier, written contract and intended data before approving Grammarly. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
