## How Zero Data Retention works

When enabled, all customer text inputs sent to our text-to-speech engine are processed in memory to generate audio. Once complete, both the text and the generated audio are immediately redacted from our logging systems. This applies to all text sent for speech synthesis, including requests using cloned voices.

## Supported models

<Note>
  TTS Zero Data Retention currently supports **TTS-1.5-Mini** and **TTS-1.5-Max** only. Legacy TTS-1 and TTS-1-Max models are not in the support scope.

## FAQs

<AccordionGroup>
  <Accordion title="How does Inworld TTS Zero Data Retention work?">
    TTS Zero Data Retention protects privacy by redacting all input texts from logs — including text sent to Cloned Voices — while only retaining the initial source audio required to build the voice itself. This is currently a workspace-level configuration managed by the Inworld Engineering team.
  </Accordion>

  <Accordion title="Can we enable Zero Data Retention for only specific customers?">
    Yes. Zero Data Retention is configured per workspace. Contact our sales team to enable it for specific workspaces.
  </Accordion>

  <Accordion title="How does Zero Data Retention affect debugging?">
    With Zero Data Retention enabled, original input text and audio output cannot be retrieved. Debugging and troubleshooting capabilities are limited to non-sensitive metadata only.
  </Accordion>

  <Accordion title="Does this affect the audio output quality?">
    No. The TTS engine still receives the text to generate the audio. The redaction happens only at the logging layer, ensuring the record of what was said is not saved.
