One Swiss Knife in the exact shape of your life.

Net Worth Tracker

A private net-worth tracker in one HTML file on your machine: assets on one side, debts on the other, no aggregator in the middle.

Live · runs in your browser · no network

This is not a screenshot. It's the real tool, running right here: go on, put something in it.

Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.

Most people know their salary to the cent and their net worth to the nearest shrug. The Net Worth Tracker keeps the whole picture — each asset and liability named, marked as which it is, valued in euros, with notes — so the big number stops being a rumor you tell yourself.

What it keeps

Standing facts

In ten years

Whatever you put in (Asset / liability, Kind, Value and Notes) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of net worth tracker entries is a decade of your own handwriting, kept in a document you can back up like any other.

If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.

Getting your data out

Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.

Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.

Questions people ask

01

How do I calculate and track my net worth?

List everything you own and everything you owe — each entry marked Asset or Liability with its value in euros. Update the values now and then, and the direction of travel becomes something you can actually see.

02

Is it safe to put my financial details into this tool?

Yes, because they go nowhere: the tracker is one HTML file running offline in your browser, with no account, no server, and no company on the other end. Your balance sheet never leaves the page.

03

How often should I update my net worth?

Monthly or quarterly is plenty — often enough to see the trend, rarely enough that market wobbles don't rattle you. Net worth is a slow story; check it like a garden, not a scoreboard.
