Does Grammarly train on my data?

Last checked: 18 October 2026 · The AI Till, UK

Defaults by account (checked 18 October 2026)

If you join a team account, you take the admin's setting.

How to turn it off

Grammarly's support page gives a different place for each account type:

1. Sign in to your Grammarly account on the web.
2. Open the page for your account type above.
3. Switch off Product Improvement and Training.

If you have a multi-user account and you're not the admin, you can't change it yourself. Ask whoever manages the account.

What turning it off does and doesn't do

Grammarly says that with the setting off, none of the content you type where Grammarly is active will be used for training or product improvement. The setting covers content processed by its generative AI features too.

What it doesn't stop:

• Grammarly reading your text. It has to process what you type to check it. The setting controls training, not processing.
• Non-content data. Grammarly says it may still collect writing statistics, such as total words written, types of suggestions accepted and mistakes made, and use those for product improvement.

What happens when you switch accounts

• Joining a team: you take the setting the organisation's admin chose.
• Leaving a team for a free account: the team's setting carries over, and you can then change it.
• Moving off an account bought through sales: Grammarly says training stays off and the toggle isn't shown.

Should a business worry?

Grammarly reads everything you type where it's active, including emails with customer details. For client-confidential or sensitive work, use a business account with training off, or switch Grammarly off in those apps.

Under UK GDPR, you're responsible for how customer personal data is handled, including by the tools you choose. See what is UK GDPR? If AI tools are used across your team, a short written policy helps. See do I need an AI policy?

Worked example

Say you're a bookkeeper in Manchester and you use free Grammarly in your browser, including when you write to clients about their accounts. You:

1. Turn off Product Improvement and Training at account.grammarly.com/security/privacy.
2. Switch Grammarly off in the client portal you use, so financial details aren't processed at all.
3. Leave it on for general emails and your website, where it's most useful.
4. Note the change and the date in your data protection records.

Common mistakes

• Assuming paid means private. Individual paid plans are on by default too.
• Thinking one team member can opt out. On multi-user accounts only an admin can.
• Forgetting the browser extension. It works across many websites, not just a document editor.
• Turning it off once and forgetting. If you change account type, check the setting again.

Is Grammarly a UK company?

No. The app is published by Superhuman Platform Inc, a US company.

Does turning it off stop Grammarly seeing what I type?

No. It still processes your text to give suggestions. The setting decides whether that content is used to train models and improve the product.

Is Grammarly safe for client work?

It can be, with the right account and settings. For sensitive work, use an account bought through Grammarly's sales team (training off by default) or turn Grammarly off in those apps. See how to use AI safely at work.
