Encrypted Voice Calls over the Tor Network
OnionPhone is a native Android application for anonymous, end-to-end encrypted push-to-talk voice and text communication over the Tor network. No servers, no accounts, no phone numbers — your .onion address is your identity.
Cross-platform compatible with TerminalPhone — call between Android and Linux/Termux using the same protocol.
