What happens to your data?

Your data, prompts, and generated outputs are used strictly to provide the platform's services and are owned entirely by you. Writer encrypts this data, keeps it isolated, adheres to a zero data retention approach, and never uses it to train AI models.

Does it train on your data?

Writer explicitly states that it does not use customer data, uploaded files, user inputs, or generated outputs to train, fine-tune, modify, or create its AI models.

Can you opt out?

Opting out of model training is not required because Writer does not use customer data, inputs, or outputs for training by default. Administrators can also set up automated data deletion schedules.

Data retention

Writer follows a zero data retention approach, storing customer data, prompts, and outputs only for as long as needed to operate the platform. Organizations can also configure automated data deletion schedules.

Encryption & security

Data is encrypted both in transit and at rest, and stored in isolated production environments. Writer holds SOC 2 Type II, ISO/IEC 27001, 27701, and 42001 certifications, as well as HIPAA Type 1 and PCI compliance.

Is it safe for work?

Yes. Writer is tailored for enterprise use, featuring zero model training on customer data, strong encryption, multi-tenant isolation, enterprise access controls (SSO/MFA/RBAC), and rigorous third-party security certifications.
