Is Grammarly Safe To Use For Free Accounts And Premium Users?

is grammarly safe to use

There’s no doubt that Grammarly is one of the most popular grammar checkers for writers and bloggers. But is Grammarly safe to use?

As with all online apps and services available on the Internet, you might have some concerns regarding your privacy and personal data.

When you install any app or program on your computer or mobile devices, it’s always worth checking the privacy policy and terms of service.

However, we all know that very few people take the time to do it, so I’ll share my experience with you.

What does Grammarly do?

Before I get to the security issues, I’ll give you a brief overview if you are not familiar with it.

Grammarly offers a completely free version that you can use by installing a simple Chrome extension. You can also install a browser extension for most of the popular browsers.

After installing it in your web browser, you can check for critical grammar issues and spelling mistakes in most online writing activities.

For students and new writers, it’s an ideal and free grammar check solution for your writing.

If you are writing a lot or plan to earn an income from your writing, you might consider the premium version.

With your Grammarly account, you will then have access to more apps and a deeper analysis of your writing, spelling, and grammar.

It’s compatible with Microsoft Office. But for most writers, you will work mostly with Microsoft Word. For Mac users, it’s also compatible with Word for Mac.

You can also integrate with Google Docs and Gmail, and there is a Grammarly keyboard app for mobile devices.

For me, I use it mostly with the WordPress editor. I find it indispensable because I can access the full editor at any time to check my writing.

Sure, it’s not a human proofreader, but it highlights so many issues and improvements I can make.

If you want to know more about all the features, you can read my Grammarly review for all the details.


Is Grammarly safe?

Yes, I believe that Grammarly is safe to use. I have used the premium version for more than five years and I have never had any security concerns at all.

But it depends on how you want to define safe.

With any application, service, or web tool you use, some of your data will be recorded. The most common is your email address and password to enable you to log in.

Other data that is usually stored by most sites and apps are your preferences. These might include your language setting, feature settings, and any special options you selected.

None of these should cause you any concern as long as the site is secure.

But some data collection does affect your privacy. The most invasive are tracking cookies that record your online behavior and search terms.

Data like this is sometimes on-sold to advertisers without you realizing it.

You can do a basic check for this data by searching your browser preferences for stored cookies.


Does Grammarly use cookies?

Yes, like any app, it stores cookies for your settings, app selections, and options.

Cookie count comparison to Google and Just Publishing

From the graph, you can see that if you are worried about cookies and tracking data, Google should be your greatest concern.

Yes, Grammarly uses cookies. But from what I can see, they are all related to functionality, and I could not find a single tracking cookie.

I included this site in the graph to give perspective and reassure you that you are not being tracked here. But yes, this site uses two cookies.

All websites use cookies, but there is one site that takes the cake.

On the scale of the invasive collection of your private data, the worst offender is Facebook. You won’t find many cookies in your browser. But by using Dev Tools, you can see what’s really going on.

If you are using Facebook and Google, then it pales by comparison when it comes to data collection.

So I can safely say that you shouldn’t have any concerns at all on this front.

Depending on your usage, you might find variations from the data I have used here.

You can also check the Grammarly browser extension permissions. In Chrome, the only two permissions are quite standard.

The two permissions set for the browser extension

Almost all extensions need to read your browsing history, and notifications are necessary to alert you to corrections. On this front, there is no concern for me at all here.


Does Grammarly store my writing?

It makes sense that Grammarly needs to send your text to its servers so that it can be analyzed for corrections.

Because it’s an online app, software needs to run to give you these results. It’s not stored on your computer like a downloadable program.

When you use the browser extension, it’s logical that it needs to access your text you are writing.

When you use the desktop editor, you can see all the projects you are working on or completed on your dashboard. Again it makes sense that these projects are saved for you.

But does it keep your text stored on its servers?

This is what Grammarly states on its support site.

Grammarly is not a keylogger.

It does not record every keystroke you make on your device. Grammarly accesses only the text you write using a Grammarly product, and only for the purposes of checking your text and providing corrections.

Additionally, Grammarly does not process anything you type in text fields marked “sensitive,” such as credit card forms or password fields.

To clarify this, there is also this tweet from Grammarly support that explains it in more detail.

From this explanation, when you delete any documents from the editor, those files will not be retained.

If you want to know more about data storage, you can read the full privacy policy or check the security page.


Can Grammarly conflict with other programs?

Is it safe to use Grammarly with other apps and programs?

The only issue I can say that I have encountered over the years is using the Editor with WordPress.

If I use the basic browser extension to click and correct critical issues marked in red, there is no problem.

But when I use the full editor and do a full scan and check, it can sometimes delete scripts from my WordPress editor.

These can include YouTube embeds or Twitter and Facebook scripts.

It’s not an issue that would affect most users. But for me, it was a little annoying at first. Now I have learned to add my scripts after I have finished doing my writing check.

If you use Developer Tools in Chrome or any other browser, it’s a good idea to disable the extension.

On occasions, I have noticed that code from the extension can affect your results. But if you use Dev Tools a lot, you know that it’s always better to disable all browser extensions.

Another small annoyance is when you use track changes in Word.

All of your edits and deletions in Word track changes are marked as “Grammarly.” If you are sharing your document with other people, you may not want this result.

However, there is a workaround that you can use. You can read about the fix in this article about changing your track change settings in Word for Grammarly.


How safe is safe?

Should you have any concerns? I can only give you my opinion as a long-time user.

If I compare how Google and Facebook track me, there’s no issue for me with Grammarly.

Because I do a lot of SEO research, my Facebook feed is full of ads for SEO products and services.

When I search for a new pair of shoes on Google, every website that carries Google Ads starts showing me ads for shoes.

Both of these sites track you by demographics, location, interests, search patterns, and a hundred other things.

I have probably checked over a million words on Grammarly. But I have never seen a connection between what I write about and online advertising.

I’m certainly not an expert on algorithms. But from my observations, I have to say that I don’t believe it is on-selling tracking data.

So by that definition, I believe it is a secure and safe app to use.

There is one proviso I have to add. I can’t vouch for the same safety for those who try to access premium features with daily Grammarly cookies.

It’s a hack to try to get free access. But there could be some security concerns attached to the browser extension you need that edits cookies.



When it comes to online security, nothing is written in stone.

Almost every week, there is news of security breaches on popular sites and online applications.

Barnes & Noble and its Nook operation suffered a cyber and ransomware attack that badly affected its users.

However, most of the successful attacks occur on sites without adequate security. But no site is totally safe from attack today.

I have read some articles that say that Grammarly is not safe to use. But they are mostly years old and fail to provide any substantial proof other than referring to an event in 2018.

Yes, there was a security bug reported in February 2018. But it was addressed very quickly with an automatic update, and no user data was compromised.

In the end, it’s about trustworthiness. On that count, I can only say that I have had no reason not to trust Grammarly.

Yes, I receive regular emails, but only for those that I subscribed to.

As far as support goes, I have only needed to use it a couple of times. In each case, the response was fast and helpful.

So, is Grammarly safe to use? Yes, I believe you can use it without any serious security concerns whatsoever.
