Parlons Desktop

Choose this if: you want your computer to be your Parlons Cloud. minimaCore Desktop and minimaDesk run a full Parlons Node with the same account services as a Cloud server: messages, calls, files, payments, paired devices and separate hosted accounts. Enable network contribution and port forwarding to provide its public relay service.

Run Cloud on your desktop

Install minimaCore Desktop or minimaDesk for your operating system. minimaDesk is also listed as MinimaClassic Desktop in the stores. You can find both through eurobuddha.
Complete the node setup and back up the seed. Use the Parlons Node kind and open the Parlons tab. Older installations may still use the classic node; follow the app's migration flow when switching an existing wallet.
Enable Contribute to the network in the desktop app's node/network settings. In Parlons → Node → Port forwarding, read the external port, internal port and Send to LAN address. Forward that TCP port on your router to the address shown, and allow it through the computer's firewall. Use the displayed values, not a port copied from another app.
Reserve that LAN address on your router and leave the computer awake and online. Check the panel for Reached from the internet. The public port serves Minima and the Maxima relay; the local account panel and admin RPC stay local. Pairing can work through other relays before forwarding, but accepting public relay traffic needs reachability.
Open Parlons → Devices, set the admin pairing password if needed, and choose New pairing code. Install Parlons Cloud on your phone, scan the invitation and connect. Repeat with a fresh invitation for each of your devices. They share this computer's account and conversations.
In Devices → Hosted accounts, enable hosting, create a separate account for your friend, then choose Show invitation or Copy tenant invite. Your friend pairs to that account. Built-in guest accounts provide chat, calls and files without your wallet or node controls; do not give friends your owner invitation.

For hosting and backups, see the Cloud manual. Calls in the desktop Parlons panel use its microphone/camera; allow access when prompted.

Alternative: standalone chat with MaximaNode

MaximaNode 1.5.118 is the separate standalone Parlons Desktop app. It can chat, share files and run a relay, but it is not the full desktop Cloud host described above. Choose minimaCore Desktop or minimaDesk for paired accounts and hosting friends.

Download the matching installer:
- Mac, Apple silicon: MaximaNode-1.5.118-notarized.dmg. Open it and drag MaximaNode into Applications.
- Windows 10/11: MaximaNode-1.5.118.msi. Open it and follow the installer.
- Debian/Ubuntu, x86-64: maximanode_1.5.118_amd64.deb. In the download folder run sudo apt install ./maximanode_1.5.118_amd64.deb.
Open MaximaNode. This is the installed name of Parlons Desktop.
In Back up your Maxima seed, write the 24 words on paper in order and keep them private.
Open the three dots menu, enter Your name and click Set.
Check Network for a connection, then add a contact below. On desktop, paste their address; there is no QR camera scanner.

Calls: standalone MaximaNode supports messaging and files, but does not carry voice or video call audio. Use one of the Android apps for calls. Keep Desktop running to stay connected; use the tray icon's Quit when you want it to stop.

For installation problems or moving an existing identity, use the Parlons! manual.

Your first conversation

Ask your friend for their contact address or contact QR, not their pairing invitation.
Open Contacts → + Add (Desktop: Add contact).
On Android, scan their QR or paste the full address. On Desktop, paste it. Tap Introduce myself.
Wait for their device to answer the introduction. If it is offline, the contact may not appear immediately.
Open the contact's chat, type a message and press the send arrow. Ask them to reply.

To let someone add you, share your address from Contacts. Keep the whole address intact. People using different Parlons versions can message each other.

Everyday use

Messages: open Chats, choose the conversation and type. A queued indicator means waiting; one tick means a relay has the message; two ticks mean the recipient's device confirmed it. A read indicator depends on read receipts being enabled.
Photos and files: open a chat and use Attach. On Android choose Photo library or Private file, select the item and send it. For Desktop's file-transfer options, see the app manual.
Calls: use Voice call or Video call in an Android chat or the Parlons panel inside minimaCore Desktop/minimaDesk, and allow microphone/camera access. The standalone MaximaNode chat app does not carry call audio or video.
Groups: on Android open Chats → New group, name it, select contacts and tap Create.
Notifications: allow notifications and background operation in Android settings. Cloud additionally needs its account host to stay online.
Payments: in a wallet-enabled one-to-one chat, choose Attach → Send payment, select Minima or MxUSD and enter the amount. Check the recipient and amount before confirming. Payments settle on the public Minima blockchain; encrypted chat does not make them anonymous. Chat-only guest accounts do not offer payments. Payment instructions.

Back up before you need it

The 24 words recover an identity, not your old chat history. Write them on paper and store them privately. Do not send them to anyone or enter them on a website. Keep any separate wallet phrase too.

Parlons! Android: Settings → Keys & security → Back up identity… creates an encrypted .pbk. It includes identity, contacts and settings, but not chat history.
Parlons Cloud: More → Settings → Keys & backup → Back up account… creates an encrypted .pbk including contacts and chat history. Media and private-file payloads are not included.
Desktop: record your seed; read backups and moving before changing computers.

Save the backup somewhere other than the device being backed up, and keep its password safe. It cannot be recovered for you. To use one account on several phones, pair them to a host; do not run copies of the same seed independently.

If something does not work

What you see	What to try
Cloud will not pair	Check the host is running, paste the full invitation and use a fresh one-time code.
An introduction is waiting	Ask the other person to open their app and check their connection.
Messages arrive only when you open the app	Allow notifications and background operation; for Cloud, check the host too.
One tick remains	A relay received it; the recipient has not confirmed receipt yet. Check their connection.
A lost paired phone	Revoke that device from another paired phone's Node tab.
