Privacy

The short version: there are no accounts, the calculators run in your browser, and the site does not currently use analytics or advertising cookies.

What the calculators do with your numbers

When you type into a calculator, the result is worked out on your own device by code that was downloaded with the page. The numbers you enter are not sent to a server in order to calculate the result, and the site has no database that stores them.

Shareable links

So that you can bookmark or share a result, a calculator may put your inputs into the page address (the part after the "?"). Two things follow from that:

• Anyone you send the link to can see those inputs.
• If the link is opened or the page is reloaded, the full address, including those inputs, is requested from the web server like any other web address, and may appear in the hosting provider's standard server logs (see below). The inputs are plain numbers such as an amount, a rate and a number of years. They are not linked to an account or a name.

You can remove the inputs at any time by deleting everything from the "?" onward in the address.

Accounts and personal information

The site has no sign-up, no login and no forms that ask for your name, email address or other personal details.

Cookies, analytics and advertising

At present the site does not set cookies, does not use analytics or tracking scripts, does not show advertising, and does not load scripts, fonts or images from other companies' servers.

This may change. If analytics or advertising are added in the future, this page will be updated before that happens to explain what is collected, by whom, and what choices you have.

Server logs

Like almost every website, this site is delivered by a hosting provider, and the hosting provider may keep standard server logs. These typically include your IP address, the date and time, the address of the page requested, and the browser and device type reported by your browser. Such logs are used to keep the service running and secure.

If you email us

If you write to [email protected], your email address and message are received and used only to reply to you and to fix any problem you report.
