UMISKY App Description (English Version)
UMISKY is a secure instant messaging app focused on end-to-end encryption (E2EE). Using AES-256 and Diffie-Hellman key exchange technology, it ensures that only the sender and recipient can read messages, files, and calls—no third party (including servers) can decrypt them. Supports multi-device sync (mobile/PC), self-destructing messages, and anonymous chat mode, balancing privacy and seamless communication.
