Privacy
Short version: the numbers you type stay on your device. This page covers calculators.debitisleft.com only.

Your inputs stay in your browser
The calculations, the results, and the Excel workbooks are all produced on your device. Nothing you type into a calculator — loan amounts, income, tax figures, business numbers — is sent to a server, and nothing is saved after you leave the page.
No accounts, no cookies
You don’t need an account or an email address to use anything here, and the calculators don’t set cookies.
Analytics
This site doesn’t run analytics right now. If that changes, it will be limited to which pages are visited and whether the Calculate or Download buttons are used — never the values you enter or your results — and this page will say so before it starts.
Hosting
The site is a set of static files served by a web host. Like any host, it may keep standard access logs — such as IP address, browser type, and the page requested — for security and reliability.
Links to debitisleft.com
debitisleft.com is a separate site. When you follow a link there — including the newsletter signup — that site’s own policies apply.
