Grammarly (free) 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. A browser extension that reads nearly everything an employee types — on a free personal account, that stream sits outside company control and outside any agreement you signed. The risk profile is unusual: it is not one paste, it is continuous capture of everything typed — emails, HR docs, legal drafts. Note also that the counterparty name has changed: the Grammarly privacy policy is now published by Superhuman Platform Inc. (formerly Grammarly), which matters if you name vendors in contracts or in your policy.
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) — A browser extension that reads nearly everything an employee types — on a free personal account, that stream sits outside company control and outside any agreement you signed. source |
| Trains on your data? | Depends on plan / settings Depends on a per-user setting. Grammarly states you can opt out of allowing it to use your content to train its models by turning off "Product Improvement and Training" in account settings — which means, on a personal account, an employee makes that call. source |
| Data retention | Governed by the consumer privacy policy of Superhuman Platform Inc. (formerly Grammarly), not by any agreement your company holds. source |
| Admin controls | None on free personal accounts. |
| Compliance certifications | The trust page references a SOC 2 report and ISO certifications for the company; we did not verify the current certificate list from a primary document on this check date. source |
| HIPAA / BAA | No — No BAA on free consumer accounts. |
Depends on a per-user setting. Grammarly states you can opt out of allowing it to use your content to train its models by turning off "Product Improvement and Training" in account settings — which means, on a personal account, an employee makes that call.
Retention: Governed by the consumer privacy policy of Superhuman Platform Inc. (formerly Grammarly), not by any agreement your company holds.
No BAA on free consumer accounts. 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 for the company; we did not verify the current certificate list from a primary document on this check date. 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 runs its controls, not what your agreement with them permits.
HIPAA is the gate: No BAA on free consumer accounts. Until a BAA is confirmed in writing, treat Grammarly (free) 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 (free) be captured for books-and-records requirements, and do the data terms hold up in vendor due diligence? None on free personal accounts.
The privilege question comes first: entering client-confidential facts into any third-party AI service must be evaluated as a potential disclosure. Because training and retention on Grammarly (free) depend on account type and settings, assume client matter data is off-limits unless your firm controls the account and has verified the terms.
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 (free) 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.
