Send and receive end-to-end encrypted messages using QR codes.
No servers. No accounts. No tracking. Your data stays on your device.
CyperQR is a privacy-first messaging tool that uses QR codes and modern cryptography to enable secure communication without servers, accounts, or internet dependency.
- How it works
CyperQR uses public/private key cryptography to encrypt messages locally on your device. The encrypted message is converted into a QR code, which can be shared via any platform (WhatsApp, email, etc.).
The recipient scans the QR code on a secure (offline) device and decrypts it using their private key.
