Two tools, one principle: your data stays yours.

Why Kalman Software

I'm a retired electrical engineer. For decades I managed my own money — trading stocks, rebalancing, planning the retirement drawdown — out of a pile of spreadsheets I kept rebuilding year after year.

When I retired I finally built the applications I'd wanted that whole time: those spreadsheets, turned into real software and shaped around how I actually work. They run entirely on your own computer, the way they run on mine — no accounts, no subscriptions, no data leaving your machine.

If they fit how you manage your money, they're yours to use.
