# Data Security Selen AI adopts a **Zero-PII Architecture** that prioritizes user privacy and data security: * **PII-Free Design**: The platform is built from the ground up to avoid the storage of personally identifiable information (PII), reducing privacy risks. * **End-to-End Encryption**: All sensitive data is encrypted both at rest and in transit using **TLS 1.3**, ensuring that data is protected during transmission and storage. * **Immutability and Traceability**: Transactional and configuration changes are hashed using **SHA-256**, creating an immutable record for tamper-proof auditability and ensuring transparent traceability of all operations. This architecture ensures high levels of security, safeguarding user privacy while maintaining integrity and transparency of platform activities. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
