Data residency

Soniox keeps your data yours. Any content you send to the Soniox API — audio, transcripts, or metadata — is never used to train or improve our models. For more information, see our Security and privacy.

What is data residency

Data residency lets you choose where Soniox processes and stores your content. When you select a region for a project, all audio and transcript data for that project stays in that region — for both processing and storage.

To get access to regional deployments, contact us: sales@soniox.com.

How data residency works

When data residency is enabled for your account:

• You choose a region when creating a new project.
• Any API requests made using that project's API key are handled fully within the selected region.
• All content data (audio + transcripts) remains within that region for processing and storage.

System data

Data residency does not apply to system data such as account and project metadata, usage statistics, and billing data. This system data may be processed outside the selected region.

Your content (audio + transcripts) never leaves the region you choose.

Using data residency

Data residency is set per project within your Soniox organization.

1. Create a project with a region

When creating a new project:

• Select the region from the region dropdown.
• Each project receives region-specific API keys.

2. Use the region-specific API domain

To ensure processing stays in the region, use:

• The API key from the regional project.
• The correct API domain for that region (see below).
