加密聊天。匿名日志。极致隐私。
NOKOSAI disappears when you leave. 彻底消失。 说出您的真意 — 而不必担心它会永远纠缠您。
厌倦了您的私密言谈变成了公开广告？
讨厌每一条消息都永世长存？
有些事物就应当消失。
Start a private ghost chat or slip into a NOKOSAI Room — a temporary public space that exists for exactly one hour, then vanishes completely.
说出您的真切想法。使用告解模式隐去姓名。在对话的律动中，看着消息渐渐淡去。毫无压力。
当您登出时，一切随之而去。无数据库，无历史记录，无凭据。您的言辞仅存在于当下 — 随后便如晨雾般消散。
一对一对话仅存储在 Redis 中。当任一方登出时，一切便不复存在。无恢复，无备份，无痕迹。
基于主题的公共房间，仅存续 1 小时。最后 60 秒将触发告别仪式。当计时归零时，房间将被彻底抹除。
在任何房间内都可隐去您的名称。以“幽灵”身份出现。它所开启的坦诚令人惊叹。后台审核依然有效 — 只是没人知道您是谁。
会话中较旧的消息会逐渐变得透明。对话在实时中自我“幽灵化”。您的屏幕变成了一段逐渐消散的记忆。
设置您的心境 — 宣泄、无聊、寻求建议或仅仅是倾听。匹配到契合的人，开启一段即逝的私密对话。结束后，各自离去。
写下一些只有在明天、下周或特定日期才会解锁的内容。将其寄往未来。让期待成为一种功能。
每一次行动都能赚取幽灵币。每一个里程碑都能解锁一枚徽章。炫耀您的历史，而不必暴露您的对话。
无私密消息数据库。 聊天内容仅存储在 Redis 中。它永远不会触碰持久化存储。绝不。
仅限于会话。 当您登出时，您的会话密钥会被清空。没有任何内容可供检索。
我们仅存储您的账号信息。 用户名、电子邮件、哈希加密密码、成就数据。这就是全部清单。
无消息分析。 我们不会为了任何目的（包括“改进产品”）而分析、分类或阅读您的对话。
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.

NOKOSAI is an ephemeral, privacy-first digital sanctuary designed as an antidote to modern corporate social media. Themed around the aesthetic of the ethereal spirit world (Yūrei, Torii gates, and hitodama spirit lights), the platform rejects surveillance capitalism and algorithmic dopamine loops, offering real-time human connection without digital footprints.
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.
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.
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.
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.
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.
Zero Tracking & No Ad Targeting: No tracking pixels (Facebook Pixel, Google Analytics, etc.), no browser fingerprinting, and zero telemetry collected to profile users.
No Data Selling: Personal information, communication graphs, and interests are never packaged, sold, or shared with data brokers.
No Vanity Competitions: No public follower counts, vanity status tiers, or popularity contests that feed social anxiety.
Anti-Doomscroll Design: Intentionally designed without infinite scroll traps, recommendation loops, or behavior-modifying engagement algorithms. You drop in, connect, and vanish when you are done.
