Money in, money out, and what's left. Everything stays on your computer.
Put this on your home screen. It opens like an app, full screen, and works with no signal. Your data stays on this phone either way.
Nothing leaves this computer. No account, no internet, no upload.

Your data stays on this computer. This file never connects to the internet and nothing you import is sent anywhere. Everything is saved in this browser's storage for this file, so clearing browser data, switching browsers, or moving to a new computer will remove it. Back up once a month to keep a copy you control.
Browser extensions can't see this page unless you've given one file access. If you're not sure, leave it that way.
This page is built so it cannot send data anywhere: the browser is told to block every outgoing connection, so even a bug could not upload your statements. On a phone, add it to your home screen and it opens like an app and works with no signal (iPhone: Safari, Share, Add to Home Screen. Android: Chrome, the three dots, Add to Home screen).
Prefer a single file on your computer instead? Download Monthly-Budget.html. Same app, same rules, and a backup made in one can be restored in the other.
