The Household Purse — one file, anywhere, forever
On The Household Purse — Bills → Spending → The Month. Fixed costs and daily spending meet in one honest number.
The Purse is a single HTML file that runs on any modern browser. On your laptop. On the other laptop. On the tablet at the kitchen counter. Offline, on all of them.
The kitchen laptop and the office laptop
Most households have more than one machine. The Purse handles that the way any file does: put a copy on each, or one in a synced folder both can see.
There is no login to fumble. Open the file. It opens.
Offline as a default, not a fallback
Wi-Fi outages, house moves, dead routers, a kid on Zoom eating all the bandwidth — none of these should stop you from checking whether you can afford the take-away. The Purse does not need the internet to answer that question.
The tool is on your device. The answer is on your device.
Backup, honestly
Family finance deserves a backup. Copy the file to a drive, an encrypted volume, or a cloud folder if you like — pick your risk tolerance. The Purse plays nicely with any of these because it is a file.
