The short version
This site does not ask you to create an account and does not send the numbers you type into the calculators to a server. The calculators run in your browser.
What is stored on your device
If you tick items on a document checklist, your browser may remember them using local storage so the list is still ticked when you return. This stays on your device and you can clear it in your browser settings.
Analytics and advertising
This version of the site does not include analytics or advertising scripts. If we add them, we will update this page to explain what is collected and why, and we will ask for consent where the law requires it.
