Crux uses a zero-knowledge security model to ensure your information stays private and encrypted at all times. This means no one (not even the Crux team) can access your documents, messages, or memories. Your nominees gain access only after a verified emergency such as death or confirmed incapacity.
Key Security Principles
1. Zero-Knowledge Architecture
Your data is encrypted on your device before it reaches Crux servers.
Crux cannot decrypt, view, or modify your data.
2. Encrypted Storage
All data is encrypted in transit (TLS) and at rest (AES-256).
3. Nominee Access Is Delayed
Nominees can only access your information:
after your death, or
after a verified emergency
Never before.
4. Device-Level Authentication
Access to your vault requires:
Your Crux login
Your MFA code (if enabled)
Operational Security Guarantees
Crux employees cannot view your encrypted documents.
Data is stored on secure servers with modern cloud security standards.
Regular penetration testing and monitoring protect against threats.
