Encrypted Chats. Anonymous Logs. Pure Privacy

SOME
CONVERSATIONS
AREN'T MEANT
TO LAST.

NOKOSAI disappears when you leave. Really disappears. Say what you actually mean — without it following you forever.

1,247 conversations vanishing right now

Tired of your private words becoming public ads?

Hate that every message lives forever?

Some things should just disappear.

How it works

THREE STEPS.
THEN NOTHING.

👻
Talk

Start a private ghost chat or slip into a NOKOSAI Room — a temporary public space that exists for exactly one hour, then vanishes completely.

🌫
Connect

Say what you actually mean. Use Confession Mode to go nameless. Watch messages fade as the conversation breathes. No pressure.

✦
Vanish

When you log out, everything goes. No database, no history, no evidence. Your words live in the moment — then dissolve like morning fog.

BUILT FOR
PEOPLE WHO
THINK TWICE.

Core
Ephemeral Private Chat

One-on-one conversations stored only in Redis. When either person logs out, everything ceases to exist. No recovery, no backup, no trace.

Rooms
NOKOSAI Rooms

Topic-based public rooms that exist for exactly 1 hour. The last 60 seconds trigger a ritual ending. When the timer hits zero, the room is erased entirely.

Identity
Confession Mode

Toggle your name off inside any room. Appear as "A Ghost." The honesty it unlocks is remarkable. Moderation still applies under the hood — just not your name.

Expression
Message Decay

Older messages in your session slowly fade in opacity. The conversation ghosts itself in real time. Your screen becomes a memory that gradually disappears.

Discovery
Mood Matching

Set your mood — venting, bored, need advice, just listening. Get matched with someone compatible for one private ephemeral conversation. Walk away after.

Time
Time-Locked Messages

Write something that only unlocks tomorrow, next week, or on a specific date. Send it into the future. Anticipation as a feature.

WE'RE HONEST
ABOUT WHAT
WE DON'T KEEP.

[✓]

No private message database. Chat content is Redis-only. It never touches persistent storage. Ever.

[✓]

Session-bound only. When you log out, your session keys are flushed. There is nothing left to retrieve.

[✓]

We only store your account. Username, email, hashed password, achievement data. That's the complete list.

[✓]

No message analytics. We don't analyze, classify, or read your conversations for any purpose including 'improving the product.'

UNTRACEABLE INFRASTRUCTURE
BY DESIGN.

NOKOSAI routes real-time messages over encrypted WebSockets directly into in-memory Redis instances without persistent database logging. Isolated Dockerized services and session-bound encryption keys guarantee that once a session ends, your chat data vanishes completely, delivering private, untraceable communication for security-focused users.

THE NOKOSAI SANCTUARY
AN ANTIDOTE TO CORPORATE SURVEILLANCE.

02 // Identity Isolation

Anonymous Registration & Dual Identity

No Social Logins or Forced Emails: Users can register and participate without linking a Google account, Apple ID, phone number, or social media profile. Your real-world identity is never tied to your digital presence.

Dual-Identity Architecture: Choose a custom visual Display Name paired with an unalterable, pseudonymous Permanent Ghostname (e.g., ghost_xxxx) generated for anonymous confessions, privacy mode, and message routing.

Zero Identity Linkage: Zero device fingerprinting, no phone-book scraping, and no cross-site tracking cookies.

No Phone Required Dual-Identity No Fingerprinting
03 // Live Frequency

Global Chat — The Transient Town Square

A Transient Town Square: A real-time, synchronous public frequency shared across the entire community.

Ephemeral Stream: Designed for immediate, live conversation rather than persistent records. The conversation lives in the moment and dissolves cleanly.

Spam & Flooding Protection: Guarded by robust rate limits, clean Markdown formatting, mentions, and ghost interactions without cluttering users' personal inboxes.

Synchronous Frequency Rate-Limited Guard No Inbox Clutter
04 // Intentional Feed

Echoes — Chronological Micro-Publishing

Chronological, Unmanipulated Feed: Posts appear strictly in linear chronological order. No hidden ranking algorithms designed to provoke outrage, controversy, or addictiveness.

Quiet Micro-Publishing: Supports clean text, images, and optimized HLS video streams with daily post pacing to prevent feed pollution and promote intentional sharing.

No Engagement Baiting: True organic expression free from sensationalist engagement traps.

100% Chronological Paced Daily Posts Zero Outrage Algo
05 // Cryptographic Shield

Private Chat — Zero-Knowledge Encryption

Zero-Knowledge Encryption: Built on client-side cryptographic primitives (X25519 ECDH key exchanges, AES-256-GCM, and client key vaults). The server routes encrypted blobs and can never read message contents.

Self-Destruction Lifetimes:
• Keep: Stored only in local client vaults until wiped.
• Ghost (Ephemeral): Disappears automatically after a set countdown (e.g., 24 hours).
• View-Once: Self-destructs immediately after decryption on the recipient's screen.

No Persistent History: Clear cache, unfriend, or vanish at any time with total client-side database wipes.

X25519 ECDH AES-256-GCM View-Once
06 // Spatial Canvas

The Constellation Void — Spatial Room Chat

Spatial Exploration Canvas: An interactive 2D starfield where users navigate as glowing hitodama spirits around Torii gates and astral anomalies.

Interactive Proximity Beacons:
• The Glimmer: Short hook visible to spirits passing by from afar.
• The Core: The deep message or conversation revealed only upon approaching.

Seance Rooms: Ephemeral, timer-based chat rooms (Open, Knock, or Invite) powered by ectoplasm energy that automatically dissolve into the void when their time expires.

EVERYTHING YOU NEED
TO KNOW.

NOKOSAI routes real-time messages over encrypted WebSockets directly into in-memory Redis instances without persistent database logging. Isolated Dockerized services and session-bound keys guarantee that once a session ends, your chat data vanishes completely.

No. Private chat messages exist exclusively in volatile memory (Redis) during active sessions. When either participant logs out or closes the room, all session keys are flushed and erased permanently.

NOKOSAI Rooms are temporary, topic-based community chat rooms that exist for a fixed 60-minute duration. When the countdown timer hits zero, the room and all contained messages are purged automatically.

Confession Mode lets users mask their username and post anonymously as 'A Ghost' within public rooms while maintaining AI-backed content moderation under the hood.
