+
+## HDS specifics (Hébergement de Données de Santé)
+
+This section outlines the specific requirements and responsibilities for hosting healthcare data in compliance with the HDS regulatory framework.
+
+### HDS Compliance Requirements
+
+When storing healthcare data within Scaleway Storage Services, the client is responsible for:
+
+*   Signing Scaleway's HDS contract.
+
+*   Ensuring access is restricted to authorized personnel.
+
+*   Creating new volumes, snapshots, or buckets specifically for uploading HDS-compliant data.
+
+*   Following Scaleway’s documentation on ensuring HDS compliance.
+
+*   Using authorized storage classes only and not using the object lifecycle rules feature.
+
+Scaleway undertakes to provide HDS-certified infrastructure, and commits to maintain this certification. The loss of said certification may result in the termination of Scaleway’s commercial relationship with the HDS client. The aforementioned elements are included in the HDS contract signed by the client.
+
+### Data Residency
+
+Scaleway guarantees that data remains within the authorized datacenters in Paris and does not access personal health data hosted by the client.
+
+You must:
+
+*   Create storage spaces (volumes, buckets, snapshots) containing healthcare data in France only. 
+
+*   Configure replication within the authorized geographical perimeter (France) only.
+
+*   Ensure backups residency remains within the authorized geographical perimeter (France only)
+
+You must not configure replication, snapshots, backups or transfer data to regions outside the authorized perimeter.
+
+### HDS-compliant Resources Identification
+
+You are responsible for:
+
+*   Knowing which Storage resources are HDS or not.
+
+*   Attaching volumes to HDS-compliant Instances only.
+
+### Block Storage Encryption and Data deletion
+
+Encryption at rest is mandatory for Volumes hosting healthcare data. Deleted data cannot be restored.  
+
+When using Block Storage, you are required to: 
+
+*   Encrypt volumes 
+
+*   Ensure secure key deletion after deleting data within your volumes to meet compliance requirements.
+
+Scaleway is responsible for:
+
+*   Encrypting at rest the physical disks on which volumes are stored with state-of-the-art compliant encryption keys.
+
+*   Managing the lifecycle, rotation and deletion of the disk encryption keys to access the underlying instances.
+
+### Object Storage Encryption and Data deletion
+
+Encryption at rest is mandatory for Object Storage buckets hosting healthcare data, with HDS-compliant key handling by Scaleway. Scaleway provides HDS-compatible mechanisms to encrypt data at rest and guarantee HDS-compliant data deletion.
+
+When using the Object Storage service, you are required to:
+
+*   Follow the guidelines detailed in the documentation in order to enforce the additional encryption mechanisms required for HDS compliance.
+
+*   Ensuring client-side data encryption or relying on existing encryption methods provided by Scaleway Object Storage.
+
+*   Enforcing additional encryption mechanisms to guarantee HDS-compliant data deletion as described in documentation.
+
+#### Data deletion
+
+*   Deletion of data stored in HDS-compliant buckets is irreversible: keys are destroyed using compliant crypto-shredding methods,
+
+*   Deleted data cannot be restored,
+
+*   The client must ensure backups before deletion. If SSE-C is used, the client must ensure secure key deletion to meet compliance requirements.
+
+Scaleway must maintain technical guarantees for secure deletion of healthcare data. 
+
+### HDS-compliant Storage Classes and Prohibited Features
+
+For the Object Storage service:
+
+*   You must use authorized HDS-certified storage classes only (Standard, One Zone). Glacier class is not HDS-compliant and must not be used by the client to store healthcare data.
+
+*   You must not use the lifecycle rules feature that is not permitted for HDS-compliant buckets hosting healthcare data.
+
+For the Block Storage service:
+
+*   You must not use legacy Block volumes and snapshots to host your HDS-compliant healthcare data.
+
+*   If exporting/importing snapshots to and from Scaleway Object Storage, you must ensure to follow the above guidelines for end-to-end compliance across the Services.
