Overview

ZDR is part of Cartesia’s broader enterprise security posture. Cartesia is GDPR, SOC 2 Type II, PCI-DSS service provider, and HIPAA compliant. For full details, visit our Trust Center. You may opt into Zero Data Retention if you require that we do not retain your content. Content means the customer-provided or model-generated text/audio payloads.

​
What is covered by ZDR?

ZDR applies to TTS and STT inference only. ZDR is not available for voice cloning, PVC, voice creation, or other workflows where customer-provided source material must be retained or processed differently. We may retain non-content operational metadata needed to run the service, including request identifiers, usage totals, account information, and service health data.

They require retaining uploaded audio samples or derived voice artifacts to function.
No. Once your organization admin enables it on the Cartesia Playground on your Enterprise account, ZDR applies to all eligible API requests automatically.
