Privacy Policy (GDPR)

Last Updated: March 16, 2026

HDTwin (a trademark of LinkedData.Center) is committed to protecting your privacy and ensuring transparency in how we handle personal data. This policy outlines our practices in compliance with the General Data Protection Regulation (GDPR).

1. Data We Collect

We collect data through two main channels:

1.1 Account Information

When you sign up for HDTwin via our OIDC provider (Auth0), we receive:

• Name and Email address
• Profile picture
• Authentication metadata

1.2 Training Survey Data

To create and fine-tune Human Digital Twins (HDT), we may conduct training surveys on physical panels. This data includes your provided opinions, preferences, and demographic information as submitted by you.

2. How We Use Data

• Account Management: To provide access to the HDTwin platform, Agora, and Studio.
• Digital Twin Generation: We use neuro-symbolic AI techniques to clone the characteristics of real panels into virtual panels of AI agents.
• Insight Generation: Aggregated data from synthetic focus groups is used to provide market and social research insights.

3. Data Protection and Anonymization

HDTwin™ uses synthetic personas. While digital twins are fine-tuned with real-world research data, they operate as autonomous AI agents. We implement strict data sterilization processes to ensure that individual personal data is not exposed or reconstructible from the synthetic insights generated by our models.

4. Your Rights

Under GDPR, you have the following rights:

• Right to Access: Request a copy of the personal data we hold about you.
• Right to Rectification: Correct any inaccurate or incomplete data.
• Right to Erasure: Request the deletion of your account and associated personal data.
• Right to Portability: Receive your data in a structured, commonly used, and machine-readable format.

To exercise these rights, please contact us at admin@LinkedData.Center.

5. Third-Party Service Providers

We use trusted third-party services to ensure the security and functionality of our platform:

• Auth0: For secure OpenID Connect (OIDC) authentication.
• LinkedInData.Center Infrastructure: Secured hosting and ACMA API integration.
