In an era where every exchange is logged, analyzed, and retained — 10 Seconds is a professional encrypted communication software designed for minimal server-side data retention, end-to-end confidentiality, and ephemeral session management. Built for organisations where confidentiality is a governance requirement.
Standard messaging platforms are engineered to retain, index, and monetize your communications. Metadata, timestamps, participants, and content are archived indefinitely — accessible to the platform, to advertisers, and potentially to third parties.
For legal teams, executive committees, M&A workstreams, HR decisions, and sensitive internal discussions, this is an unacceptable exposure.
Every design decision was made with a single principle: the server should never be able to read, retain, or betray your communications.
NaCl asymmetric encryption (Curve25519/XSalsa20/Poly1305). Your private key is generated on-device, encrypted with your password, and never transmitted in plaintext.
Every message is automatically destroyed 10 seconds after display. No history. No scroll-back. No forensic recovery. Configurable up to 20 seconds.
Every chat room has a hard 30-minute ceiling. On expiry, all session data is purged from server memory — no server-side archive, no server-side backup. This is a design feature, not a guarantee against device-level or network-level capture.
Messages are relayed in real time and are not written to any persistent database. The server processes encrypted relay traffic only. Server-side message content is not retained beyond the active session.
SHA-256 client-side hashing (WebCrypto native) before transmission. Server re-hashes with bcrypt cost 12 (bank-grade, above OWASP 2026 standard) inside an isolated thread pool. Raw passwords never sent or stored at any point.
If all participants leave the session, the server purges the session within 30 seconds. Session metadata is not retained beyond the session lifetime.
Every session renders an invisible watermark containing the participant's username and the date — burned into every screenshot taken. If a capture is shared externally, its origin can be traced back to the exact account and session. All participants are notified in real time when a screen capture is detected.
Ephemeral messaging alone can't stop a determined participant from taking a screenshot. 10 Seconds goes further: every capture is traceable, every capture is signalled live to everyone in the room.
A watermark carrying the viewer's username and date is rendered across every chat page. Invisible on screen, visible on any screenshot or screen recording. Burned into the capture itself.
The client detects capture attempts via PrintScreen, visibility change, and window blur events. The second a capture happens, every participant in the room is notified live — with the name of who did it.
A leaked screenshot found anywhere online can be traced back to the exact account that took it. Supports internal disciplinary review; evidential value in formal proceedings depends on the applicable jurisdiction and procedural rules.
No marketing claims. Here is every cryptographic primitive at every layer. Verify it in the Security Overview and reproduce it from the open specifications below.
Every design decision maps to a published 2026 standard. No proprietary cryptography, no undocumented posture.
Not just the standards we follow — the operational posture we maintain over time, verified on every deployment.
Four steps. Authentication required. Username is pseudonymous — no real identity required.
Create a named session with a strong password. Your device generates a unique key pair — private key never leaves your device.
Share the session name and password out-of-band — verbally, or via a separate secure channel.
Exchange end-to-end encrypted messages, images, audio, documents, and video. The server relays ciphertext only — it does not hold decryption keys.
Close the session manually or let the 30-minute timer expire. Server-side session data is purged from server memory. Note: device-level or network-level capture by third parties may independently persist data.
