Expense Splitter
A private expense splitter in one HTML file on your machine: no account, no cloud, no server to talk to.
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.
Four friends, one cabin weekend, eleven receipts, and a group chat slowly turning into a courtroom. Expense Splitter keeps track of who paid for what and works the tangle down to who owes whom, so the trip is remembered for the trip. Fairness, it turns out, is mostly arithmetic done in front of everyone.
Standing facts
- One HTML file. Opens in any modern browser, on any operating system.
- No account. No login, no sign-up, no e-mail wall.
- No cloud. Nothing leaves your browser: no server, no telemetry, no analytics.
- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Whatever you put in 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 splitter 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
How does the Expense Splitter settle up a group trip?
You record who paid for what along the way, and the splitter untangles it into who owes whom. The maths is done in the open, which is what keeps it friendly.
Do my friends need to install anything or sign up?
No. There are no accounts at all — one person keeps the list in the one file, and the settling-up is read aloud or passed around. Considerably less friction than getting four people onto an app.
Where is the shared expense data stored?
Only in the browser of whoever holds the file. The splitter is a single offline HTML file — nothing is uploaded, nobody's spending is on a server, and the file is owned outright, forever.
