2. Roles and Responsibilities

2.1 Controller Obligations

The Controller:

• Determines the purposes and means of processing Personal Data submitted through the Service
• Is solely responsible for ensuring it has a lawful basis for processing Personal Data, including obtaining all necessary consents from Data Subjects

• Not process Personal Data for any purpose other than providing the Service
• Ensure that personnel authorized to process Personal Data are bound by confidentiality obligations
• Implement the technical and organizational security measures described in our Security page
• Assist the Controller in responding to Data Subject rights requests to the extent technically feasible
• Notify the Controller of any Personal Data breach without undue delay (and in any event within 72 hours of becoming aware)
• Delete or return all Personal Data upon termination of the Service, as directed by the Controller, subject to retention periods required by law

3. Sub-Processing

The Controller authorizes MediChat to engage the sub-processors listed below. MediChat will inform the Controller of intended changes by updating this DPA, providing 14 days' advance notice for material changes. All sub-processors are bound by data protection obligations at least as stringent as those in this DPA.

4. Data Subject Rights

MediChat will assist the Controller in fulfilling Data Subject rights requests — including access, rectification, erasure, portability, restriction, and objection — to the extent technically feasible. Controllers are responsible for responding directly to Data Subjects.

5. Security Measures

MediChat implements the technical and organizational measures described in our Security page, which are incorporated herein by reference, including encryption at rest and in transit, access controls and least-privilege principles, and incident detection and response procedures.

6. International Data Transfers

Where Personal Data is transferred outside the EEA, UK, or other applicable jurisdiction, MediChat will rely on appropriate transfer mechanisms, including:

• EU Standard Contractual Clauses (SCCs) (European Commission Decision 2021/914)

8. Audit Rights

MediChat may satisfy audit obligations by providing relevant certifications, security documentation, or third-party audit reports, rather than permitting on-site audits, unless required by a supervisory authority.

9. Liability

Each party's liability under this DPA is subject to the limitations of liability set out in the Terms of Service. Nothing in this DPA limits either party's liability to Data Subjects or supervisory authorities under applicable law.
