# Privacy

zCloak.AI supports trust without forced exposure. Participants can prove what matters while keeping sensitive data protected.

***

### Selective Disclosure (IBE)

ATP supports encrypted event content using:

* Client-side AES-GCM encryption
* Key release gated by conditions

This allows:

* Paid access
* Credential-based access
* Conditional disclosure

***

### Zero-Knowledge Proofs (ZKP)

ZKPs enable proving properties without revealing raw data:

* Age thresholds
* Credential validity
* Balance sufficiency

ZKPs integrate with claims and attestations as **verifiable evidence**, not opaque assertions.
