-
At home on your device
Your books stay local and work offline.
-
Directly, person to person
You choose what to share and who has access.
-
A hand with your accounts
From documents to drafts. From questions to reports.
Features
The whole of your bookkeeping, in one desktop app
Journals, accounts, transfers and ledgers; reports, backups and sharing, all on a local database that opens whether or not you are online.
Your data stays yours
Everything sits in a SQLite database on your machine. No cloud account, no accounting records held on a server.
Share directly
Invite someone with a short code and grant read, write and delete separately. The connection is made between the two devices.
Built-in AI assistant
Attach your invoices, statements and receipts and let the assistant draft the transfers, query your accounts and put together a report.
Reports made to print
Reports come out with their tables, headings and charts in place, and print to paper or PDF through a page layout of their own.
Backup and restore
A backup is a zip of plain JSON documents, readable by anything that opens a zip. Restore only ever adds, so nothing you already have is overwritten.
How It Works
The server introduces you; the books talk device to device
netbalance.net does one thing: it helps two devices find each other. There are no accounts, and the journal itself never passes through it.
Your deviceThe original journal
Encrypted, direct connection
The person you share withLive access, with your permission
-
No sign-in
There is no account to make and no email address to give. You press Connect, and that is all.
-
You invite someone
Pick what they may do and press Invite. The app shows a short code, good once and for ten minutes; give it to them.
-
You confirm
They enter the code, and their device shows four digits. Type those in, and the journal is shared.
-
The devices meet
The two apps connect directly, and the journal is read and written live on the device that owns it. On the same network they find each other without the server at all.
A shared journal is not copied
A journal shared with you is not downloaded to your device: every screen asks the device holding it, live. What you see is what it holds right now; in exchange, that device has to be online.
One copy, no conflicts
Because the ledger lives in one place, there are no versions to reconcile. A change made on one side is read straight from the source the next time the other side opens that screen, with no background layer trying to merge copies.
Assistant
September income of ₺182k is the highest of the last six months.
An assistant that reads your documents and knows your books
The assistant runs inside the app and reaches the same things you do: it queries accounts, searches entries, drafts transfers and produces reports. Sign in with your Google account and it uses Gemini models.
- Calculator
- Journal and account lookup
- Entry search
- Transfer drafts
- Report generation
- Exchange rates
- Gold prices
- Crypto prices
- Turkish legislation search
Reports come with their charts
The reports the assistant produces carry charts alongside their tables. A chart is embedded as SVG rather than as a screenshot, so it stays sharp when you print the report or save it as a PDF.
The assistant builds the chart from the entries in your journal; you only say which accounts and which period you want to see.

Legislation, read from the source
Turkish law (kanun, KHK, tüzük, yönetmelik, presidential decrees and tebliğ) is searched as published in the Resmî Gazete, and the assistant cites the mevzuat.gov.tr link for whatever it relied on.
Attach your documents
Images go to the model as they are; PDF, Word, Excel, PowerPoint, OpenDocument, CSV, HTML, Markdown and archives are converted to text first. Up to 10 MB per file.
Because the assistant runs on your own Google account, the Gemini CLI free tier applies: 60 requests a minute and 1,000 a day. Beyond that, Google One subscriptions are available.
Security
Exactly what the server sees, written down
"Your data is safe" is easy to say. These two lists are the whole of what the server actually does, and what it genuinely cannot see.
What the server does
- Tells two devices where the other one is, so they can connect directly.
- Hands out the short-lived number at the front of an invite code.
- Sees addresses and tags that change every hour and lead back to no one.
- Never carries anything between two devices.
What the server cannot see
- Your journals, accounts, transfers and amounts.
- Your reports and the documents you attach.
- The contents of what flows between two devices.
- Who you are: there are no accounts or email addresses.
- Invite codes and confirmation codes.
- Your backup files: those stay on your disk.
Keys for every share
Every share has its own key pair on each of the two devices, so a device is not recognisable from one share to the next. The connection between them is encrypted end to end.
Said plainly
The server is not trusted with access. It can fail to introduce two devices, but nothing it says lets a third one in. Devices that cannot reach each other directly cannot share: nothing is ever relayed through a server.
Frequently asked questions
Before you begin.
A few things to know about your device, your books, and sharing.
Can I use NB offline?
Yes. You can open the journals stored on your own device offline. To open a shared journal, both devices need to be connected: on the same network that is enough, otherwise both need the internet. The AI assistant also requires an internet connection.
Does sharing send a copy of my journal?
No. The journal stays on your device. The person you invite reads entries directly from your device and can edit them if you grant permission. You control read, write, and delete permissions separately.
Why can't I reach a shared journal?
The two devices connect to each other directly. Some networks, such as mobile hotspots and strict office firewalls, do not allow that. NB never routes your books through a server instead, so from such a network the shared journal can't be opened; on the same network as the other device, or on most home connections, it can.
Which computers does NB support?
NB is available for macOS, Windows, and Linux. The macOS build supports both Apple Silicon and Intel processors. Published builds and download links are listed in the section below.
How do I back up my books?
The app exports your records as a zip file containing JSON documents. Keep that file somewhere safe. Restoring a backup adds new records without overwriting existing ones.
Download
Install NB
Free to download, and it keeps itself up to date once installed. The macOS build is universal: it runs on both Apple Silicon and Intel machines. The Android app doesn't update itself yet: install each new version from here, over the old one, and your journals stay. Android asks once to allow installing apps from your browser.
NB is currently in beta. It is fit for daily use
but still changing, and your books live only on your own device,
so keep regular backups.
