All Grammarly users have great control over their data. Grammarly makes each user feel secure about their privacy by following stringent protections. The text or content that you upload to Grammarly, either its free version or premium version, has rights over that text, including the copyrights and duplication privileges. In short, users’ work remains with users only. Grammarly also restricts the user’s data over their network, infrastructure, and services.
When you start using Grammarly, you will see a visible icon of Grammarly displaying for suggestions. You can turn it off and switch it on at any time whenever you need. When you are using sensitive sites, you can consider switching Grammarly off, which is a good practice.

However, this is not the case with Grammarly.

Grammarly Security Risks: Are There Any?
1. Data access
When you use Grammarly or any other writing tool, the text you type is transmitted to its servers for processing, which raises concerns about data access and storage. While Grammarly does use strong encryption to protect the users data in transit and limits retention by storing text temporarily, sensitive or confidential information typed into the platform could still pose a potential threat if mishandled by the internal employees working at Grammarly. To use Grammarly, one has to give extensive permission, such as accessing all data on the website you visit, which could introduce vulnerability if explored. Despite these risks, Grammarly has implemented several security measures, including compliance with GDPR and CCPA, SOC 2 Type 2 certification, and strict access controls to ensure user privacy.
However, users are advised to avoid using Grammarly for sensitive or confidential content, review permissions regularly, and consider alternative offline solutions for high-security needs. Keeping Grammarly updated and leveraging its premium security features can also help minimize potential risks while ensuring data privacy.
2. Security breach
Grammarly is a very popular writing assistant that millions of people use daily to review spelling and grammar mistakes and fix punctuation errors in their daily writing work. Being an online assessment tool, it is possible that some security breaches could happen with Grammarly. One such incident happened a few years back when experts at Salt Security discovered some flaws in Grammarly.
The flaws could have allowed Grammarly and other integrated apps to leak people’s credentials and enabled attackers to fully take over accounts. Salt Labs, the security company’s research team, noted that thousands of other websites using widely seen social sign-in mechanisms are likely vulnerable to the same type of attack, putting billions of individuals around the globe at risk.
3. Threat from employee
Grammarly ensures that each employee working at the company does not have access to users data. However, we want to highlight the fact that no system is entirely immune to risk and several scenes could potentially expose user data. Human error, such as misconfiguring security settings or database permissions, could inadvertently expose sensitive information.
Moreover, Grammarly, being a high-value target, is vulnerable to many cyberattacks like phishing scams, social engineering, and exploitation of software systems, which could grant unauthorized access to its system. Insider threats also pose a risk, as disgruntled or malicious employees with access to critical systems might misuse their privileges to extract or expose data.
Furthermore, Grammarly’s reliance on third-party vendors for managing infrastructure introduces potential supply chain vulnerabilities, where a breach in a vendor’s system could compromise Grammarly’s data security. Even with tightly controlled processes, employee access to user data for troubleshooting purposes inherently carries a risk of accidental exposure or misuse. To mitigate these risks, users should avoid entering sensitive or confidential information into Grammarly’s platform and rely on alternative tools for handling highly sensitive data.
