Mathematical Proof
Over Blind Trust.
iDuno is engineered with a strict zero-knowledge architecture. Our servers act as an illiterate postman: transporting opaque ciphertext envelopes between devices without possessing the mathematical keys to read or archive them.
Client-Side Web Crypto (ECDH P-256)
Asymmetric keypairs are generated exclusively inside the browser's volatile memory (window.crypto.subtle). Raw private keys never touch disks, databases, or cookies.
BEAM Blind WebSocket Relay
Our real-time backend runs on the Erlang/OTP BEAM concurrency engine. Each room is an isolated actor process executing in RAM that relays ciphertext payloads without inspecting contents.
Automatic OTP Dissolution
Rooms are bounded by strict OTP timers. When the timeout triggers or either peer clicks "Destroy Room", the actor process terminates immediately and VM garbage collection purges memory buffers.
Zero Disk Persistence (0 Bytes)
No message tables, no disk caches, no session history logs. Subpoenas or forensic seizures cannot extract records that literally do not exist in our physical infrastructure.
Interactive Cipher Playground
Test real-time client-side encryption and witness how ciphertext looks before leaving your device.

Type any sensitive data below. Observe how your browser seals it before transmission, what our servers actually handle, and how RAM memory purges in a millisecond.
Keys generated in browser volatile heap. Random 96-bit IV attached.
The Erlang server only routes this unreadable binary stream.
Upon 10-minute timeout or 1 click, OTP supervisor terminates and frees memory.
How iduno Differs From Standard Messaging
Most “private” messaging apps protect transit, but tie your identity to your phone number and store conversations on persistent storage.
| Dimension | Traditional Apps (WhatsApp / Signal) | iduno Black Box |
|---|---|---|
| Personal Identity Required | Phone number, carrier SMS, or email | Zero credentials, zero registration |
| Conversation Storage | Device disk + iCloud / Google Drive backups | Volatile RAM only — 0 bytes on disk |
| Server Metadata Logging | Who spoke to whom, timestamps, IP graph | Zero metadata logged or indexed |
| Subpoena Vulnerability | Subject to court orders & backup warrants | Mathematically impossible: zero data exists |
| Session Lifecycle Limit | Indefinite or optional manual timer | Hard 10-minute maximum OTP self-destruct |
| Cryptographic Keys | Linked to SIM card & device hardware | Ephemeral ECDH P-256 in browser volatile heap |
Built For When an NDA Is Not Enough
Standard enterprise messaging preserves records forever. iduno is built for high-stakes moments where persistence is a liability.
Confidential Deals & Financials
Exchange wire details, seed phrases, cap tables, and private term sheets without leaving permanent trails on corporate Slack or Google Workspace.
Whistleblowing & Journalism
Share off-the-record intelligence without attaching your personal phone number, carrier SIM metadata, or Apple/Google identity graph.
Out-of-Band Incident Response
When internal company Slack, Teams, or email are compromised by a breach, establish an instant, uncompromised emergency out-of-band channel.
