An offline budgeting app that lives on your computer.
No bank feeds, no cloud, no monthly rent. You type what you spent — the file does the rest, and it stays yours forever.
The strange thing about modern budgeting apps is that they insist on knowing every transaction the moment it happens. That's convenient the first week and quietly invasive by month three. An offline budget flips it: nothing leaves your machine, and the small friction of typing a number is the whole point — it's how you start noticing where the money goes.
What "offline" actually means here
The whole application is a single HTML file. Open it in any browser, on any laptop, with the wi-fi off. No installer, no login screen, no account to recover, no company that can lock you out. Your budget is a file — the same shape as a document or a photo. You back it up the way you back up the rest of your life.
Envelope discipline without the surveillance
The Household Purse (the Offline.Ltd Blade for money) does envelope budgeting the honest way: money in, money assigned, money spent, rollover at month end. Same discipline YNAB teaches, none of the bank-linking or annual renewal.
The thirty-day out
Every knife on this site carries a thirty-day, one-e-mail refund. Try it for a month; if it doesn't fit the way you keep house, we send the money back and the file stays with you either way.
What to reach for
Common questions
Does it connect to my bank?
No — deliberately. Every transaction is typed in (or pasted from a CSV export). That's the offline part; it also happens to be why people who use it end up more aware of what they spend.
Where is the data stored?
Inside the HTML file itself, on your computer. Nowhere else. If you copy the file to a USB stick, your entire budget travels with it.
What about mobile?
The file opens fine in mobile browsers and works offline there too. Most people use it on a laptop and glance at it on the phone — it's an offline document, not an app store app.
