Nymchat Brand Assets
Last Updated: August 21st, 2026
Here you will find the Nymchat brand assets, the guidelines for using them, and what you need to know about permission. Nymchat Brand Assets means the Nymchat word mark, the Nymchat wordmark and app icon, and the other artwork and design elements associated with Nymchat.
The app itself is free software under the AGPL-3.0 and you can do a great deal with it. The trademarks are separate from the code, and this page is about those.
Brand assets

Nymchat trademarks
These are the marks owned by 21 Million LLC:
| Mark | What it names |
|---|---|
| Nymchat | The app, in all its forms. |
| NYM | The short form of Nymchat. |
| Nymbot | The AI assistant built into the app. |
| Nostr Ynstant Messenger | What NYM stands for. |
| Decentralized. Pseudonymous. Unstoppable. | The Nymchat tagline. |
Nostr is an open protocol and nobody's trademark. Bitchat is a separate project with its own owners; Nymchat is compatible with it, not affiliated with it. Bitcoin and Lightning are likewise not ours, and the app store names belong to their respective companies. Nothing on this page grants or restricts anything about them.
Usage guidelines
General
- DO use the Nymchat trademarks to refer to Nymchat itself, or to products and services that genuinely work with it. A client that speaks the same protocol may say so.
- DO set the marks apart from the text around them — capitalise them, italicise them, quote them, or set them in a different face — so a reader can see where the name ends and your prose begins.
- DO use the assets from this page as they are, scaled proportionally.
- DON'T use a name, wordmark or icon confusingly similar to Nymchat's, for any purpose.
- DON'T use or register the Nymchat marks as, or as part of, social media account names, profiles, usernames or handles.
- DON'T combine the Nymchat assets, or any part of them, with another logo, company name or mark, or use them in any way that implies partnership with or endorsement by 21 Million LLC, without explicit written permission.
- DON'T describe your app or product as being "for Nymchat" when it is not built to work with Nymchat.
- DON'T put the Nymchat assets on merchandise — apparel, stickers, accessories, packaging — or otherwise monetise them, without explicit written permission.
- DON'T use Nymchat or the other marks in a domain name.
Referring to Nymchat
Spell and capitalise the marks exactly as they are written above. Use them as adjectives, not as nouns or verbs, and never in a way that suggests a generic or descriptive meaning.
- "Send encrypted messages with the Nymchat app."
- "Join a geohash channel using a Nymchat client."
- "Send a Nymchat."
- "Nymchat your friends."
Using the wordmark
Use the official wordmark from this page. Do not alter it in any way other than scaling it proportionally.
Clear space
Keep a clear space around the wordmark of at least half its height on every side. Nothing else — text, borders, other logos — belongs inside it.
Minimum size
The wordmark and the icon are built out of small glyphs, and below a certain size they stop being legible and start being noise. Never render the app icon smaller than 48 px, and never render the wordmark narrower than 240 px.
What not to do
Using the Nymchat brand in media
You may not use the Nymchat wordmark, icon or app imagery in a film, television programme, book, play or other visual media without explicit written permission. To ask, write to support@nymchat.app and we will review the request.
Ordinary journalism, reviews and commentary about Nymchat do not need permission. Use the assets from this page, and do not imply that we endorsed what you wrote.
Colours
The palette has a dark and a light form. The values below are the dark ones; the light-mode equivalents are in the site's stylesheet.
Typography
Nymchat is a terminal by inheritance, and the type follows from that.
- Monospace — Courier New, Consolas, Monaco. The wordmark, headings, labels and anything that should read as a terminal.
- Sans-serif — the platform UI stack: SF Pro Display, Inter, Segoe UI, system-ui. Body copy and interface text.
The mobile apps bundle Roboto for the interface and Noto Sans as a broad fallback, so glyphs the primary face lacks still render rather than turning into empty boxes. Colour emoji are left to the operating system's own font.
Using the Nymchat source code
Nymchat is licensed under the GNU Affero General Public License v3.0, and we are glad to see people build on it. The licence sets the terms: among them, if you run a modified version as a network service, you must offer its source to the people using it.
The licence covers the code. It does not grant any right to the trademarks. If you run your own build, make it clear that you own and operate your service and that it is not Nymchat, and do not use the Nymchat name, wordmark or icon as the identity of your service, product or application. You are welcome to state factually that it is based on Nymchat's source.
The app can prove which build it is running, and a byte-identical copy served from another domain says so plainly rather than passing itself off as the official app. See Verifying the build.
