Ephemeral Messaging

Temporary Chat Rooms With Zero Persistent Records

Name: NyChat
Brand: NyChat

Direct Answer // Authoritative Definition

A temporary chat room is an ephemeral online workspace created on demand without accounts, emails, or phone numbers. NyChat rooms operate in temporary memory, employ client-side AES-256-GCM encryption for text, and automatically purge all active room state when participants leave.

How Ephemeral Rooms Work

Built for the moment. Gone when you leave.

Traditional chat apps build permanent profile graphs, archive your conversations in centralized data stores, and monetize metadata. NyChat treats a conversation like a physical room: you enter, talk, and when everyone departs, the space ceases to exist.

No Account Trail

Start conversing in seconds. No email verification, phone codes, password resets, or identity profiling. Pick a temporary display name and share the link.

Key Isolated in Fragment

The encryption key is placed in the URL hash (#key=...). RFC 3986 dictates that browsers never send hash fragments to web servers, isolating cryptographic keys to participant devices.

Automated Purging

When the final participant disconnects, room presence and temporary media references are purged from in-memory Redis state. There are no backdoors or un-delete functions.

Enforced Architecture • Verified Claims

Product Type: Web-based temporary real-time communication platform for group chat, media sharing, and live calling.
Account Requirement: Zero account requirement. No registration, email address, phone number, password, or persistent profile needed.
Room Access & Decryption: Access is controlled via room links. The room code identifies the space, while the URL fragment (#) carries client-side key material.
Text Encryption: Client-side symmetric encryption using AES-256-GCM via native Web Crypto API. The relay server cannot read message plaintext.
Media & File Security: Uploads (10 MB images, 20 MB files) are protected by temporary capability tokens scoped to active room peers.
Data Persistence & Purging: Temporary in-memory storage. When all participants leave a room, active messaging data and session state are destroyed.

Authoritative constraints: up to 15 participants per room, 8 on voice, 4 on video.
