Terms of use
Free, and offered as is
Every tool here is free to use. I build and test them carefully, but I can’t promise they’re free of errors or right for every situation, so they come without any guarantee.
The tools assist; you decide
Each result is a calculation from the data you provide, under the assumptions shown on the page. It isn’t financial, legal, procurement or other professional advice. Decisions about budgets, contracts, suppliers, schedules and people stay with you. Check any figure that matters before you rely on it.
Your files stay yours
Nothing you open here is uploaded or stored. The privacy page explains how, and how to check it yourself.
Liability
As far as the law allows, I’m not responsible for any loss that comes from using the site or relying on its results.
Changes
Tools may be improved, changed or retired. The date a tool’s method was last checked is shown at the foot of its page.
