Question 1

What is NyChat?

Accepted Answer

NyChat is a web-based communication platform that lets people create temporary, real-time rooms for conversation without requiring user accounts, passwords, or persistent profiles. Rooms and messaging state are held in memory and destroyed when participants leave.

Question 2

Do I need an account or email to use NyChat?

Accepted Answer

No. NyChat requires zero account registration, email address, phone number, or password. You pick a temporary display name for the active room session and begin conversing immediately.

Question 3

How do I create and share a temporary chat room?

Accepted Answer

Click "Create a room" on the homepage, choose your temporary display name, and click Start Room. NyChat generates a temporary room and gives you a complete secure invite link. The URL fragment (#) contains the client-side decryption key, ensuring only invited peers who receive the full link can decrypt room messages.

Question 4

How does a NyChat room work?

Accepted Answer

Rooms are temporary real-time workspaces hosted in temporary memory. The server coordinates room routing, WebSocket signaling, and capability checks, while text encryption and WebRTC media streams run directly in participant browsers. When all participants disconnect, the room is permanently closed.

Question 5

How many participants can join a NyChat room?

Accepted Answer

A single NyChat room supports up to 15 simultaneous participants. Within the room, up to 8 participants can join a voice call simultaneously, and up to 4 participants can join a video call simultaneously.

Question 6

Is NyChat end-to-end encrypted?

Accepted Answer

Text messages are encrypted client-side using AES-256-GCM via the native Web Cryptography API before transport. The relay server receives only ciphertext and cannot read message plaintext. Voice and video calls use WebRTC DTLS-SRTP encryption in transit. However, media uploads and voice notes are access-controlled via temporary capability tokens, not client-side encrypted at rest.

Question 7

What encryption algorithm does NyChat use for text messages?

Accepted Answer

NyChat uses AES-256-GCM with a 256-bit symmetric room key generated via crypto.getRandomValues(). Each message payload includes a unique 12-byte initialization vector (IV) and authenticated data binding the ciphertext to its room and crypto version.

Question 8

What is the difference between a room code and a complete secure invite?

Accepted Answer

The room code (in the URL path, e.g. /room/K7QXM4DN) identifies the room on the server for network routing. The complete secure invite includes the key fragment (e.g. #key=...), which holds the client-side decryption key. Browsers never transmit URL fragments to servers, so joining with a room code alone fails closed without the key.

Question 9

Can NyChat servers read encrypted text messages?

Accepted Answer

No. The server stores and relays ciphertext, an IV, and a crypto version label. Because the encryption key remains in the client-side URL fragment and is never transmitted to the host, the server lacks the cryptographic key needed to decrypt text messages.

Question 10

What does NyChat explicitly not promise?

Accepted Answer

NyChat does not claim perfect anonymity, untraceability, screenshot prevention, or media end-to-end encryption. It processes limited operational metadata to run the service and mitigate abuse, participants can capture their screens, and losing your secure invite makes encrypted room history unrecoverable.

Question 11

Are NyChat images and files end-to-end encrypted?

Accepted Answer

No. Uploaded images (up to 10 MB) and documents (up to 20 MB) are access-controlled and temporary, not end-to-end encrypted. They are stored temporarily and require short-lived, revocable capability tokens scoped to active room participants for access.

Question 12

Can I send voice notes in NyChat?

Accepted Answer

Yes. You can record, pause, resume, preview, and cancel audio notes up to 3 minutes (8 MB limit) directly within the room composer. Voice notes are delivered through NyChat's session-bound capability-protected media pipeline and are destroyed when the room expires.

Question 13

Are voice notes end-to-end encrypted like text messages?

Accepted Answer

No. Voice notes are audio file uploads protected by room capability tokens and active session authorization, not client-side encrypted at rest. They are purged automatically when the room closes.

Question 14

How do NyChat voice and video calls work?

Accepted Answer

Voice and video calls use WebRTC mesh peer-to-peer connections between participant browsers. The NyChat backend handles connection signaling (offers, answers, ICE candidates) and coordinates call state, but audio and video streams flow directly between participants. Voice calls support up to 8 peers; video calls up to 4.

Question 15

What are the file size and message limits?

Accepted Answer

Text messages support up to 6,000 characters. Images can be up to 10 MB, files and documents up to 20 MB, voice notes up to 3 minutes (8 MB), and custom display pictures up to 2 MB. Up to 5 attachments can be sent per message.

Question 16

What happens when a room closes or expires?

Accepted Answer

When all participants leave a room or the room reaches its inactivity window, the room is destroyed. In-memory message logs, participant states, and temporary uploads are deleted. Documented exceptions: reported content retained as a bounded moderation snapshot (up to 90 days) and standard operational server logs.

Question 17

How does in-room reporting work?

Accepted Answer

Any participant can report abusive content. A report captures a bounded server-side snapshot (up to 20 messages of surrounding context) retained for moderation review for up to 90 days. Session tokens and URLs are stripped, identifiers are HMAC-hashed, and text messages remain encrypted in ciphertext format within the snapshot.

Question 18

What happens if I lose my secure invite link?

Accepted Answer

The room encryption key exists exclusively in the complete invite link. If you lose it and clear your browser session, the encrypted session is permanently unrecoverable. NyChat has no user accounts, passwords, or recovery mechanisms to restore lost keys.

Question 19

Does NyChat track users or build advertising profiles?

Accepted Answer

No. NyChat does not use tracking cookies, does not sell user data, and does not create persistent user profiles. For aggregate site performance, privacy-first Umami analytics is used without storing IP addresses or personal identifiers.
