Protecting your data and privacy

Data security

Through industry-standard data protection, secure infrastructure, and third-party verification, Grammarly ensures data security across our product ecosystem.

Data ownership

Your words are yours—we do not, and will not, sell your or your team’s content. We don’t help third parties advertise their products to you.

Features that enhance security and control

Grammarly gives you control over how your employees use the product so you can better protect your company's work.

Team administration

Administration tools make it easy to add, remove, or transfer accounts and to manage team member roles, permissions, and access within your company.

SAML single sign-on

SSO allows for access management and enforcement of company-specific controls through integrations with identity providers.

Two-step authentication

For an extra layer of safety, multi-factor authentication is available for team members across your company to secure their individual access.

Custom security controls

Use your own security key, and choose how long employees can stay logged in before needing to reauthenticate.

Secure Infrastructure

Grammarly’s infrastructure is built to protect your data according to high industry standards.

Data hosting

Grammarly hosts data in Amazon Web Services data centers in the US East region and ensures continual product availability by using native backup tools. An industry-leading infrastructure provider, AWS is certified as compliant with ISO 27001 and has received a SOC 2 (Type 2) report.

Data encryption

Grammarly encrypts all data in transit and at rest. Data transfer is protected using the industry-standard TLS 1.2 protocol, while data at rest in AWS is encrypted using AES-256 server-side encryption. Grammarly uses AWS Key Management Services for database encryption and secure key management. Enterprise clients can either provide their own encryption keys or use a Grammarly-managed key to control and view access to data stored at rest in Grammarly’s service.

Cloud platform

All components that process your data operate in Grammarly’s private network inside our secure cloud platform, and each user’s data is isolated from other users’ data. Grammarly’s servers and network ports are behind load balancers and a web application firewall. Grammarly thoroughly reviews all data subprocessors to conduct due diligence.

Third-Party Validation

External penetration testing

Grammarly continually works to identify and fix security vulnerabilities in our product and infrastructure. That’s why we undergo third-party network penetration tests as well as AWS security and corporate infrastructure security assessments and audits.

Bug bounty program

Grammarly’s ongoing HackerOne bug bounty program promotes transparency and provides a channel for external security researchers to identify potential security concerns. Our team responds rapidly—and resolves these issues before they can be exploited. If you believe you’ve discovered a security-related issue, please report it at HackerOne or contact us at security@grammarly.com.
