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 rent is predictable, the groceries are not, and somewhere between them the month goes quietly sideways. The Household Purse brings fixed bills and daily spending together into one honest number for the month. Not a lecture, not a forecast — just the truth of where the household stands, updated as you spend.

Questions people ask

01

How does The Household Purse work day to day?

You set down your fixed bills once, then log spending as it happens. The two meet in a single figure for the month, so 'can we afford it' stops being a feeling and becomes a glance.

02

Is The Household Purse suitable for a family rather than one person?

Yes — it's built around the household, not the individual. One purse, everyone's spending, one number the whole kitchen table can agree on.

03

Is my family's financial data safe in The Household Purse?

It never goes anywhere. The tool is one HTML file running offline in your browser — no account, no cloud, no company database with your grocery bills in it. The file, and everything in it, is yours for good.
