Grammarly Business can be used at work only under specific conditions. Our verdict for a typical 50–500 person company handling client or regulated data, assessed 29 July 2026: Limited. Moving shadow Grammarly use onto a business account is the right direction, but the public documents we could read do not establish the two things an Approved verdict needs: a categorical no-training term for business content, and a documented admin control surface. Both have to come from your contract before this is safe for confidential text. If your team writes client-facing text all day, converting shadow Grammarly use onto a company-held account is still the highest-value move available — it just needs two contract terms to become an approval rather than a tolerance. Note the counterparty name while you are drafting them: the privacy policy is now published by Superhuman Platform Inc. (formerly Grammarly).
This verdict reflects Grammarly (Superhuman Platform Inc.)’s published terms as we read them on 29 July 2026. A vendor can change its terms the day after; the primary sources below are how you check.

| Our tier verdict | Limited (assessed 29 July 2026) — Moving shadow Grammarly use onto a business account is the right direction, but the public documents we could read do not establish the two things an Approved verdict needs: a categorical no-training term for business content, and a documented admin control surface. Both have to come from your contract before this is safe for confidential text. source |
| Trains on your data? | Not established from a primary source Grammarly states it does not sell or monetise user or customer content, and publishes a "Product Improvement and Training" opt-out in account settings. We could not verify, from a primary document, any statement that business-plan content is categorically excluded from model training — get that term in your Customer Business Agreement rather than assuming it. source |
| Data retention | Not documented on the public trust page. Retention is set by the customer business agreement, so it is a contract term you negotiate rather than a published figure you can look up. source |
| Admin controls | Single sign-on IS documented — both the public trust page and the privacy policy describe SSO for business accounts. What we did NOT find in either document we read is SCIM provisioning or a described admin console for offboarding, so confirm those two specifically in writing before you rely on being able to deprovision accounts at scale. |
| Compliance certifications | The trust page references a SOC 2 report and ISO certifications; we did not verify the current certificate list from a primary document on this check date. Ask for the report under NDA — that is the normal path anyway. source |
| HIPAA / BAA | Not publicly documented — Not publicly documented in the sources we could verify on this check date. Do not treat Grammarly Business as HIPAA-eligible without a signed BAA in hand. |
Grammarly states it does not sell or monetise user or customer content, and publishes a "Product Improvement and Training" opt-out in account settings. We could not verify, from a primary document, any statement that business-plan content is categorically excluded from model training — get that term in your Customer Business Agreement rather than assuming it.
Retention: Not documented on the public trust page. Retention is set by the customer business agreement, so it is a contract term you negotiate rather than a published figure you can look up.
Not publicly documented in the sources we could verify on this check date. Do not treat Grammarly Business as HIPAA-eligible without a signed BAA in hand. As a rule: no signed Business Associate Agreement means no protected health information (PHI) — a BAA is the gate, not the security posture. A vendor can hold every certification on the market and still be the wrong place for PHI, because what makes PHI processing lawful for a covered entity is the contract, not the encryption.

Not verified from a primary document on this check date. The trust page references a SOC 2 report and ISO certifications; we did not verify the current certificate list from a primary document on this check date. Ask for the report under NDA — that is the normal path anyway. Ask for the current SOC 2 report under NDA before you rely on it. A certification is also not a contract: it describes how Grammarly Business runs its controls, not what your agreement with them permits.
HIPAA is the gate: Not publicly documented in the sources we could verify on this check date. Do not treat Grammarly Business as HIPAA-eligible without a signed BAA in hand. 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? Single sign-on IS documented — both the public trust page and the privacy policy describe SSO for business accounts. What we did NOT find in either document we read is SCIM provisioning or a described admin console for offboarding, so confirm those two specifically in writing before you rely on being able to deprovision accounts at scale.
The privilege question comes first: entering client-confidential facts into any third-party AI service must be evaluated as a potential disclosure. Because the vendor’s published documents do not answer whether Grammarly Business trains on what you put in, a firm cannot represent to a client that it does not. Keep matter data out until you hold that answer in writing.
Every vendor claim above traces to a document the vendor publishes, and every document below is one we actually opened and read — each carries the date we read it. All of them were read on 29 July 2026. The verdict date on this page is not a build stamp and is not "today": it is the oldest of those dates, because a verdict is only as current as the stalest document under it. Rebuilding the site does not move it.
Where a fact is not in one of these documents, the page says so rather than filling the gap. That is why some rows read "not publicly documented" or "not established from a primary source" instead of naming a certification or rounding an open question to a convenient answer.
Why the tier verdict is "generic": Limited 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 25 other tools specifically for your industry, company size, and the data your team handles.
And a verdict has a shelf life: vendor data policies change quietly — a terms update can move a tool between tiers overnight. This page states what we read on 29 July 2026. The $149/mo Monitor plan exists precisely because that date keeps receding.
