Don't Trust. Verify.
Every security claim is backed by independently verifiable evidence.
Verified Evidence
Screenshots from Activity Monitor during active transcription.
Zero Network Traffic
Claim:: Airgap Voice makes zero outbound network connections.
Evidence:: Activity Monitor → Network tab shows 0 bytes sent during transcription.
Zero Disk Writes
Claim:: Audio data is never written to disk.
Evidence:: Activity Monitor → Disk tab shows 0 disk writes during transcription.
Local GPU Processing
Claim:: All inference runs on the local Apple Silicon GPU.
Evidence:: Activity Monitor → GPU tab confirms Metal GPU utilization during transcription.
Trust Artifacts
Evidence your security team can verify independently.
Code Signing & Notarization
Signed with a Developer ID certificate and notarized by Apple. The stapled ticket enables offline verification on any Mac.
codesign -dv --verbose=4 /Applications/Airgap\ Voice.app
Zero Network Traffic
No open sockets, no bytes sent or received. Verify independently with lsof, nettop, or tcpdump.
lsof -i -P | grep "Airgap" && nettop -p $(pgrep "Airgap Voice") && sudo tcpdump -i any -p "Airgap" || echo "Not Found"
Entitlement Verification
The signed binary contains no network entitlements. Only app-sandbox, audio-input, and file-read entitlements are present.
codesign -d --entitlements - /Applications/Airgap\ Voice.app
Security Guarantees
Architectural commitments enforced by design, not policy.
No Network Access
The macOS kernel enforces zero network access. The signed binary contains no network entitlements. Any code path that attempts a network connection is terminated by the operating system.
No Persistent Storage
Audio is never written to disk, cache, or temporary files. Processing happens exclusively in volatile memory.
Offline Installation
Install and run without ever connecting to the internet. The full ML model ships with the application bundle.
FIPS 140-2 Foundation
Built on Apple CryptoKit and the Secure Enclave. Designed to align with FIPS 140-2 cryptographic standards.
