## What is hqChat?

HQChat is a private messenger built for a future where today's encryption can be broken.
Every message, photo, and call is end-to-end encrypted on your device using post-quantum
HQC key exchange and AES-256-GCM. Your encryption keys are generated on your device and
never leave it — not even our servers can read your conversations.
