Mango Punch

Mango Punch lets two devices connect with a 6-digit code—no sign-up—and transfer files directly over WebRTC.

Features

• Send / receive photos, videos, audio, contacts (vCard), and general files

• OTP rendezvous pairing

• End-to-end encryption on the transfer path (ECDH + AES-GCM)

• File bytes are not uploaded to a Mango Punch file cloud

• Optional deep link: mangopunch://

Notes

• Public MQTT signaling and STUN/TURN may be used for connectivity; operators may see connection metadata (e.g. IP, timing). File payloads travel on the encrypted P2P channel.

• The in-app File category may require Android All files access so you can browse and select items to send. The app does not open, preview, execute, or install selected files.

• The app does not claim automatic nearby-device discovery. You connect only with the peer who shares the code.
