Is Writer SOC 2 compliant? Yes, plus HIPAA and the full ISO trust triad.
Writer completes an annual SOC 2 Type II audit that also covers HIPAA/HITECH, and holds the full ISO trust triad: ISO/IEC 27001, 27701 and 42001. Because it is certified to ISO 42001 (AI management) as well as the information-security and privacy standards, Writer meets all seven of the seven criteria on this site, including the AI-specific governance criterion that most vendors still miss.

How Writer handles your data, in detail
Does Writer train its AI models on my data?
No, not by default. Writer trains its own Palmyra family of large language models rather than reselling a third-party model, which lets it offer a zero-data-retention posture. By default it does not train or improve its models on customer data, so there is no separate training opt-out to request.
Is Writer HIPAA compliant, and does it support regulated sectors?
Yes. Writer's annual SOC 2 Type II audit includes HIPAA/HITECH, and Writer publishes domain-specific models for regulated sectors such as Healthcare and Finance. Teams handling protected health information should confirm a Business Associate Agreement directly with Writer before deployment.
Where is my data stored, and does Writer offer data residency?
Writer positions data residency and zero data retention as first-class enterprise governance features, and lists US and EU regions. Because residency options vary by contract and region, confirm the specific hosting region and residency guarantees directly with Writer before purchase.
