Xybern uses artificial intelligence and machine learning to provide our Services. Here's how we handle your data in relation to AI:

6.1 How AI Processing Works

• Verification Processing: Content submitted via the API is analyzed using multiple verification paths including semantic analysis, web evidence grounding, rule engines, and multi-modal checks.
• Web Grounding: During verification, the API may fetch publicly available web sources to cross-reference claims. These fetches are transient and not stored beyond the verification session.
• Bias Analysis: Content may be analyzed for 8 categories of bias (gender, race, age, disability, religion, socioeconomic, nationality, sexual orientation). Bias scores are returned in the response and logged.
• PII Detection: If PII/PHI detection is enabled, the API scans content for personally identifiable information. Detected PII is reported but not stored separately unless redaction is requested.
• Multi-Model Routing: We may route prompts to multiple AI models to achieve consensus and improve accuracy.
• Workspace Isolation: Your data is logically isolated from other customers' data.

6.2 Model Provider Agreements

Our agreements with AI model providers include:

• OpenAI — Language model processing
• Anthropic — Language model processing
• Google (Gemini) — Language model processing
• Meta (Llama) — Language model processing (via hosted inference)
• DeepSeek — Specialized reasoning

All model provider agreements include:

• Strict prohibitions on using customer data for model training
• Data processing agreements compliant with GDPR
• Confidentiality obligations
• Security requirements

6.3 Automated Decision-Making

Our Services may involve automated processing, but we do not make decisions with legal or similarly significant effects based solely on automated processing without human review.

7.3 Legal Requirements

We may disclose data when required by law, legal process, or government request, or to protect the rights, property, or safety of Xybern, our users, or others.

7.4 Business Transfers

In the event of a merger, acquisition, or sale of assets, your data may be transferred as part of the transaction. We will notify you of any such change.

7.5 With Your Consent

• If PII/PHI detection is enabled, detected sensitive data is flagged but not extracted or stored separately
• Enterprise customers can configure data residency and retention policies for API data

15.5 Verification of Third-Party Content

• When web grounding is enabled, the API accesses publicly available web sources
• We do not store scraped web content beyond the verification session
• Web source URLs consulted are logged as part of the verification record

We may update this Privacy Policy from time to time. When we make material changes:
