One Swiss Knife in the exact shape of your life.

Expense Logger

A private expense logger in one HTML file on your machine: no account, no scan-and-upload, no cloud middleman.

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.

The parking ticket from the client visit is in a coat pocket, becoming lint. Expense Logger gives every business expense a proper row while the memory is fresh: what it was, the amount, a category — supplies, travel, software, fees, or other — and the date. Come tax season, you'll be the rare person who isn't excavating pockets.

Manual:

What it keeps

Standing facts

In ten years

Whatever you put in (Expense, Amount, Category and Date) 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 expense logger 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

What categories does the Expense Logger use?

Five plain ones: supplies, travel, software, fees, and other. Each expense gets a description, an amount, a category, and a date — enough structure to be useful, not enough to be a chore.

02

Will the Expense Logger help me at tax time?

It keeps the raw record your tax return is built from — every expense dated and categorised as it happened. Your accountant gets a tidy list instead of a shoebox.

03

Is my expense data stored in the cloud?

No cloud at all. The logger is one HTML file that runs offline in your browser; your amounts and categories stay on the page. No account needed, and the file is yours forever.
