Engineering

Built by cryptographers, designed to withstand adversaries.

A look under the hood at the cryptographic primitives, edge AI, and hardware attestation that make CloakLoc uniquely defensible.

System architecture

Five layers, zero trust assumptions.

Compromise of any single layer does not compromise your privacy. Defense in depth, from hardware to network.

Layer 01

Application Layer

Hardened mobile app with minimal attack surface

Layer 02

On-Device Intelligence

Edge AI, mobility synthesis, anomaly detection — all on your handset

Layer 03

Crypto Core (Rust)

Memory-safe primitives, hardware-bound keys, post-quantum hybrid

Layer 04

Attestation & Provenance

TPM, Secure Enclave, device integrity verification

Layer 05

Privacy Relay Network

Multi-hop VPN, Tor bridges, zero-log anonymous relay infrastructure

The stack

No black boxes. No magic.

Every component is documented and purpose-built for privacy.
