What happens to your data?

Writer processes customer data and prompts strictly to provide services within an isolated production environment. All customer data, files, inputs, and outputs remain the property of the customer and are not retained longer than necessary. Customer data is never used to train or refine Writer's models.

Does it train on your data?

Does not train on your content. Writer does not use user inputs, generated outputs, or customer data to create, modify, or train its AI models.

Can you opt out?

Not applicable. Writer does not train its models on user data, inputs, or outputs by default.

Data retention

Writer operates on a zero data retention approach, storing customer data only as long as needed to build and operate on the platform. Organizations can also configure automated data deletion schedules.

Encryption & security

Data is encrypted in transit and at rest, and provisioned 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 provides strong enterprise protections, including data isolation, encryption at rest and in transit, independent SOC 2 and ISO certifications, and a commitment not to train models on customer content.
