¶ Client Quick Start
Welcome! In this article, we will go through Polynom's core fundamentals and get you onboard.
We'll cover just the basics:
- Minimum requirements
- Where can I download Polynom?
- First run with the Polynom Wizard
- Joining a Polynom server
- Backing up your Graphatar™
Important topics we won't cover in this Quick Start Guide (but recommend you read up on in our Wiki):
- Detailed import and export of Graphatars
- Adding and editing Social Encryption™ keys
- How permissions work from a user's perspective
¶ Minimum Requirements
Polynom uses cutting-edge post-quantum cryptography and thus requires reasonably up-to-date operating systems to function.
Currently, there are Polynom clients for Windows 10+, Linux (~Debian 12+), MacOS, Android 9+ and iOS.
On very new Windows systems, S Mode may be on by default, preventing you from installing Polynom until you disable S Mode for the installation. If you encounter an S Mode error, please visit
Switching out of S Mode in Windows for instructions relevant to your version of Windows.
¶ Where can I download Polynom?
Go to https://polynom.app and download the client for your operating system.
¶ First run with the Polynom Wizard
After installing Polynom, double-click on the desktop icon to start the app. On the first run, you will be shown the Wizard where you can create your Graphatar (identity) and then join a server.
- Enter your user name;
- Choose among the options, then use the refresh icon to roll new Graphatars;
- Take your time! There is no back button;
- When you find a Graphatar you like, click next;
- You can now choose some theme colors, and/or click next;
- You will see that the demo.polynom.app read-only server is preselected for you;
- Choose this read-only server if you do not have a private server address to add manually;
- Click finish;
- You are now in the app itself and need to click on the server's icon in the top toolbar to see it;
- Navigate around the read-only server to familiarize yourself with Polynom!
¶ Joining a private Polynom server
The demo.polynom.app server is read-only and is for demonstration purposes. Polynom is meant to be self-hosted, so it may take some time before a lot of private servers become available for use.
To join a privately run server:
- Click the + icon on the toolbar;
- Enter the URL of the server and if necessary, edit the port number;
- Click "Join Server" and its icon will appear on the toolbar;
- Select that icon to view the new server.
¶ Backing up your Graphatar
It is very important that you export your Graphatar and protect it with a strong password.
- Click on the Settings gear icon in the tool bar;
- In the Settings pane, click on your Graphatar to reveal Manage Identities;
- Select Manage Identies and then right-click on the Graphatar you wish to export;
- In the context menu, choose Export to open the export dialog box;
- Enter a strong password and store it safely, then click Export;
- Save the User.nom file some place safe.
You've done it!
