Is Grammarly safe, and who holds your text now?

By Alberto Gulotta · Updated 16 September 2026 · 13 min read

People asking is Grammarly safe are almost never asking about viruses. They are asking a sharper question that the word “safe” hides: this thing reads everything I type, so where does it go, who keeps it, and is it being used to build something.

The answer is available, it is specific, and it changed recently in a way that almost nothing written about this subject has caught up with. So start with the change, because it determines which document you should be reading.

This matters for a practical reason rather than a dramatic one. If you went looking for Grammarly’s privacy policy, you would end up reading Superhuman’s, and if you had bookmarked an older summary of Grammarly’s terms, you would be reading about a document that no longer governs anything.

The company’s own policy is one answer. The people whose job is to decide whether it may run on a university’s machines are another, and the three university IT pages read for this guide do not agree with each other.

So: is it safe? The question only becomes answerable once you replace it with a better one, which is safe for what. Three situations, and the honest answer differs in each.

Personal writing. Emails, applications, essays about your own life. The arrangement above is the one you are accepting, and whether it is an acceptable trade for a tool that genuinely improves their writing. If you would rather your sentences not become training material, the control exists and turning it off costs you nothing.

Work under an obligation. This is where the answer changes, and it changes hard. If you have signed a confidentiality agreement, handle client material, or work with anything regulated — legal drafts, patient records, unreleased financials, unpublished research — the relevant question is not whether the company is trustworthy. It is whether pasting that text into any third-party service is permitted by the agreement you signed. Very often it is not, and the tool’s privacy policy has no bearing on that at all. Your employer’s policy decides it, and the enterprise version of a product usually exists precisely because the consumer version does not satisfy it.

Student work. A separate issue again, and one people conflate with privacy. The risk here is not that your essay leaks; it is that heavy suggestion-taking on a graded piece of writing may fall foul of an academic integrity policy that says the words must be yours. That is a rules question rather than a security question, and the guide on where the line sits covers it.

What to actually do, in order. Open your account settings and find the training control, because it is the only lever on this page that changes anything and it takes under a minute. Then decide, once, what you are willing to paste — a rule of your own is more reliable than judging every document as it arrives. If work material is involved, check your employer’s policy before the tool’s, because that is the one with consequences attached. And treat the browser extension as the widest part of the surface: it sees far more fields than the ones you consciously use it on.

One thing worth saying plainly, because this subject attracts more alarm than it deserves. Nothing quoted above is unusual. Nearly every free writing tool is funded the same way and states similar terms in similar language, and this company has written down a clearer commitment on selling user content than most of its competitors have. The reason to read the policy is not that this one is worse. It is that the differences between them are exactly where the decision lives.

Every quotation above carries the date the document was read, and the policy itself carries an effective date of 6 July 2026. Privacy policies change without announcement, and a page about them that does not say when it was written is not telling you enough to act on.

Not covered here. It will not tell you the tool is dangerous. Nothing in the policy supports that, and saying it would be the easiest traffic on this page and the least honest.

It will not tell you it is fine either. Whether it is fine depends on what you paste into it, and that is a question about your obligations rather than about the software.

And it will not carry an affiliate link to a writing tool, which for this particular search is one of the better-paid links on the site — the coupon site currently on page one is there for a reason. What holds instead is simple: every quotation on this page is taken from the current privacy policy or from the university IT page that published it, each with the date it was read.
