Spojiti, the post-quantum messenger that knows no one, is in public beta on Android, iPhone, Mac and Windows
CognitionX Logic India Pvt Limited, an Indian start-up headquartered in Bengaluru, has opened the public beta of Spojiti, an end-to-end encrypted messenger for Android, iPhone, Mac and Windows that requires no phone number, e-mail address or account. Identity is a cryptographic key derived on the device from a twelve-word recovery phrase; the company's servers route sealed messages between random identifiers and delete them on delivery; encrypted attachments are deleted within six days of upload.
Spojiti ships post-quantum protection for every user in every supported build, in every chat between people: a hybrid ML-KEM-1024 and X25519 key agreement, a post-quantum ratchet that renews the protection on every turn of each conversation, and ML-DSA-65 signatures beside Ed25519 on the account's signed prekeys, each verified against NIST's published test vectors on the device at every launch. Only the official :Spojiti_Beta channel is still classical. Each of those three layers, the key agreement, the ratchet and the signatures, pairs a post-quantum algorithm with a classical one, so breaking either alone opens nothing.
The Spojiti Private Messenger Core, the app and relay code that prove the zero-PII design, is open source under the GNU AGPL v3 at github.com/Spojiti, so anyone can read exactly how a message is sealed and routed. An independent security audit of the full product is in progress, expected by end of 2026 and on track; the report will be published on spojiti.world in full, findings included.
"Everyone encrypts the message. Nobody else erases the person," said Hemanth Kashyap, founder and CEO. "Spojiti knows no one. That's the whole point."
Every feature of Spojiti is free for everyone: sealed chats and groups, voice and video calls, screen share, photos, videos and files, voice notes, backups, and every privacy and safety control. Five packs, Basic, Pro, Plus, Max and Ultra, raise the limits for a year, each including the packs below it: bigger files, more devices and accounts, unlimited groups of up to 256, unlimited call recordings, screen shares, Flashes and live location, custom themes, and encrypted backup space on Spojiti.cloud. A pack is bought in the app, through the App Store on iPhone and by card or net banking elsewhere, or on our website as a pack code; none of it needs a Spojiti account, and a blind signature means our records cannot link a payment to the account that uses it.
Spojiti runs on multi-homed infrastructure the company owns and operates. The beta is available now at spojiti.world: a signed app for Android, Apple TestFlight for iPhone and iPad, a notarised app for Mac, and a portable app for Windows 10 and 11.
