VoidSend

About this app

VoidSend is a zero-knowledge encrypted messenger built for a post-quantum world. Every message, file, and call is encrypted on your device before it ever leaves — our servers act as a blind relay, mathematically unable to decrypt your data. ZERO-KNOWLEDGE ARCHITECTURE Unlike other messengers that promise privacy, VoidSend's Blind Relay design means the server only ever sees encrypted blobs. No plaintext. No metadata leaks. Your encryption keys never leave your device. POST-QUANTUM ENCRYPTION VoidSend uses hybrid encryption combining X25519 with ML-KEM-768 (Kyber), protecting your conversations against both today's threats and tomorrow's quantum computers. Messages are sealed with AES-256-GCM, and identities are verified with ML-DSA-65 post-quantum signatures.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
