# Health data hosting

> Host your organization under HDS, the French certification for health data

Health data hosting (HDS) is the French certification for hosting health data.
Under HDS, your organization's sessions stay in the EU, with
[Data residency](https://docs.gradium.ai/guides/data-residency.md) on **Strict** and
[Zero data retention](https://docs.gradium.ai/guides/zero-data-retention.md) on. It is available on our
paid plans, and Gradium enables it after reviewing your request.

## Request health data hosting

Sign in to [Gradium Studio](https://studio.gradium.ai/), open the Profile
dropdown in the top right, and select **Organization**. Then:

1. Under **Data controls** > **Health-data hosting**, click **Request access**.
2. Optionally, add a note: your use case, a deadline or a compliance
   requirement.
3. Click **Send request**.

We reply by email with the next steps. Once HDS is enabled, the card shows
**Enabled**.

Only organization admins can send the request. If you are a member, ask an
admin of your organization. See [Organization](https://docs.gradium.ai/guides/organization.md) for
roles.

On a free plan, **Request access** is greyed out. Hover it to see why, and use
**Upgrade plan** at the top of the **Data controls** section.

## What changes under HDS

* **Data residency** stays on the EU with **Strict**. Its settings are greyed
  out.
* **Zero data retention** stays on.
* **Your plan** stays paid: the subscription page shows a notice instead of
  **Cancel plan**, and the free plan is available once HDS ends.

## Leaving health data hosting

Leaving HDS follows its own procedure. On the **Health-data hosting** card:

1. Click **Disable hosting**.
2. Optionally, tell us why in the note.
3. Click **Send request**.

![The request to disable health-data hosting, with Disable hosting, the note and Send request numbered 1 to 3](https://mintcdn.com/gradium/btVTyxbdLpGHgmWj/images/guides/health-data-hosting/leave.png?fit=max\&auto=format\&n=btVTyxbdLpGHgmWj\&q=85\&s=78600ffec48aad2cbf71f9ce6dde1f5a)

We reply by email to plan it.
