1 - 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.

3 - EU AI Act Compliance

HDTwin is designed with a “Compliance by Design” approach, ensuring full alignment with the European Union Artificial Intelligence Act (EU AI Act).

1. Risk Classification

HDTwin is classified as a Low-Risk AI System.

Our technology, which combines neuro-symbolic AI with large language models (LLMs), is used for:

• Synthetic market research
• Opinion gathering and consensus detection
• Stakeholder simulation

It does not engage in any prohibited practices or high-risk applications as defined by the EU AI Act (e.g., biometric identification, social scoring, or critical infrastructure management).

2. Transparency Obligations

In accordance with Article 52 of the EU AI Act, HDTwin fulfills all transparency requirements:

2.1 Explicit Disclosure

All partiuser of the deliberation and studio applications are informed that they are interacting with AI-generated synthetic personas. These “Human Digital Twins” are clearly identified as computer programs and not real individuals.

2.2 Neuro-Symbolic Explainability

Our patent-pending technology provides analytical evidence for the reasoning of each individual AI agent. This neuro-symbolic approach ensures that AI insights are not “black boxes” but remain explainable and auditable.

3. Data Quality and Governance

HDTwin ensures high standards of data governance:

• Bias Sterilization: We use advanced techniques to mitigate implicit biases within the underlying AI models.
• Validation: Virtual panels are fine-tuned and scientifically validated against real-world field research to guarantee alignment.
• Human Oversight: The platform is designed to be a tool for human analysts (e.g., market researchers, political strategists), ensuring that ultimate insights and decisions remain under human control.

4 - Terms of Service

Effective Date: March 16, 2026

Welcome to HDTwin. These Terms of Service (“Terms”) govern your access to and use of the HDTwin platform, including the Agora (Synthetic Focus Groups), Studio (Agent Configuration), and all related services provided by LinkedInData.Center (“we,” “us,” or “our”).

By accessing or using our services, you agree to be bound by these Terms.

1. Description of Service

HDTwin provides a platform for generating market and social research insights using Human Digital Twins (HDTs)—AI agents fine-tuned to represent specific personas or panels. Our services include “Panel Cloning,” “Synthetic Engagement,” and “Consensus Detection.”

2. Platform Usage and Accounts

• Eligibility: You must be at least 18 years old to use the platform.
• Account Responsibility: You are responsible for maintaining the confidentiality of your login credentials (via Auth0) and for all activities that occur under your account.
• Prohibited Use: You may not use the platform to generate deepfakes, disseminate misinformation, or engage in any activities that violate the EU AI Act or other applicable laws.

3. Intellectual Property

• Platform IP: HDTwin, its neuro-symbolic AI technology, and all software, documentation, and design assets are the exclusive property of LinkedInData.Center.

6 - Ethics & AI Safety

At HDTwin, we believe that synthetic research must be grounded in ethical responsibility and scientific rigor. Our “Human Digital Twins” are designed to provide insights that are helpful, honest, and harmless.

1. Bias Sterilization Technology

LLMs often carry implicit biological, cultural, and historical biases from their training data. HDTwin implements a proprietary Bias Sterilization layer that:

• Neutralizes Toxins: Filters out harmful or discriminatory language at the agent level.
• Corrects Stereotypes: Adjusts the distribution of agent responses to ensure they don’t default to common LLM tropes, instead aligning with the statistical realities of the target panel.
• Neuro-Symbolic Anchoring: Uses symbolic logic to ensure agents stay within the “logical guardrails” of their assigned persona.

2. Explainable AI (XAI)

We mitigate the “black box” approach to LLM AI. Every Human Digital Twin is accompanied by a semantic definition that is available to the “studio” application users.

3. Human Oversight

HDTwin is a Human-in-the-loop platform. Our tools are designed to assist researchers, not replace human judgment:

• Researcher Control: Decisions on survey design, agent configuration, and insight interpretation always remain with the human user.
• Auditability: Complete logs for AI operations allow for retrospective review and quality control.

4. Prohibited Uses

We strictly prohibit the use of HDTwin for:

• Generating content intended to deceive or manipulate democratic processes.
• Creating deepfakes or impersonating specific real-world individuals without consent.
• Developing applications that violate the fundamental rights defined by the EU Charter.

5. Continuous Monitoring

Our AI Ethics Committee regularly reviews our bias mitigation strategies and the outputs of our models to ensure they meet the evolving standards of AI safety and fairness.
