Grammarly Business is generally safe for workplace use on a corporate plan. Our verdict for a typical 50–500 person company handling client or regulated data: Approved. Corporate account with admin controls and published enterprise security posture — the manageable way to say yes to a tool employees already want. If your team writes client-facing text all day, this is usually the highest-value "Approved" conversion from shadow use.

| Our tier verdict | Approved — Corporate account with admin controls and published enterprise security posture — the manageable way to say yes to a tool employees already want. |
| Trains on your data? | No (per vendor terms). Grammarly states business/enterprise customer content is not used to train models without permission and is excluded from human review by default under its enterprise terms. |
| Data retention | Enterprise retention and deletion commitments are documented in Grammarly’s business terms; admins can manage members and offboard accounts. |
| Admin controls | Admin console, SSO/SCIM on qualifying plans, member management, and analytics. |
| Compliance certifications | SOC 2 Type 2; ISO 27001 (per Grammarly’s published trust documentation) |
| HIPAA / BAA | Grammarly advertises HIPAA support on qualifying enterprise arrangements — confirm BAA availability for your plan with Grammarly before allowing PHI anywhere near it. |
Grammarly states business/enterprise customer content is not used to train models without permission and is excluded from human review by default under its enterprise terms.
Retention: Enterprise retention and deletion commitments are documented in Grammarly’s business terms; admins can manage members and offboard accounts.
Grammarly advertises HIPAA support on qualifying enterprise arrangements — confirm BAA availability for your plan with Grammarly before allowing PHI anywhere near it. As a rule: no signed Business Associate Agreement means no protected health information (PHI) — regardless of how good the vendor’s general security posture is.
HIPAA is the gate: Grammarly advertises HIPAA support on qualifying enterprise arrangements — confirm BAA availability for your plan with Grammarly before allowing PHI anywhere near it. Until a BAA is confirmed in writing, treat Grammarly Business as off-limits for anything containing PHI — patient names, appointment details, clinical notes, even "anonymized" summaries that could be re-identified.
For SEC/FINRA-regulated firms the questions are recordkeeping and confidentiality: can communications through Grammarly Business be captured for books-and-records requirements, and do the data terms hold up in vendor due diligence? Admin console, SSO/SCIM on qualifying plans, member management, and analytics.
The privilege question comes first: entering client-confidential facts into any third-party AI service must be evaluated as a potential disclosure. Grammarly Business’s no-training terms on corporate plans help, but confidentiality duties still require client-consent and matter-sensitivity judgment.
Why the tier verdict is "generic": Approved is the right starting classification for most 50–500 person companies — but a healthcare company, a law firm, and a SaaS startup should not have identical tool lists. The $79 policy kit classifies Grammarly Business and 24+ other tools specifically for your industry, company size, and the data your team handles.
And it goes stale: vendor data policies change quietly — a terms update can move a tool between tiers overnight. The $149/mo Monitor plan exists precisely because this page is only accurate as of July 2026.
