Security

Last updated: July 8, 2026

Encryption Model

Secure Pair Transfer is built for encrypted communication between two paired clients. Chat messages and file payloads are encrypted by the clients before traveling through the relay.

The relay is intended to route encrypted traffic, manage pairing sessions, provide license checks, and distribute updates. It is not intended to decrypt private chat or file contents.

What The Service Can Still See

No practical relay can be completely blind to everything. The service may process account, license, update, pairing, timing, connection, IP, device, file-size, and transfer-status metadata when needed to operate, secure, debug, and support the product.

Beta Security Limits

The Windows beta is not code-signed yet. Windows may show unknown publisher warnings until Khuna Labs finishes its code-signing path. Only install builds downloaded from this site or another official Khuna Labs source.

Do not treat beta software as your only copy of important files. Keep backups and test with files you can afford to resend.

Responsible Use

Secure Pair is a private transfer tool, not permission to transfer anything unlawful or harmful. You are responsible for the files, messages, and contacts you choose to use with the software.
