Voice calls use WebRTC.

English, Simplified Chinese (简体中文), and Vietnamese (Tiếng Việt). The app auto-detects your system locale, and you can override it manually in Profile → Language.
All traffic is encrypted in transit (TLS 1.2 / 1.3). Passwords are stored as bcrypt hashes; we never see plaintext. See our Privacy Policy for full details on what data we collect and why.
