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.

All components that process your data operate in Grammarly’s private network inside our secure cloud platform, and each Grammarly 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. Read more about the subprocessors Grammarly uses.
