Calculations happen in your browser. Your numbers are never transmitted.

What we do not collect

Every calculator on this site runs client-side. The figures you type into an input field stay in your browser: they are not sent to a server, not logged, and not stored. When you enter values, they are written into the page's URL so that the link can be shared or bookmarked — that URL exists only in your browser and in whatever service you choose to send it through.

What we do collect

• Server logs — standard web server records including IP address, requested URL, user agent and timestamp. This is how any web server operates and is used for security and troubleshooting.
• Aggregate analytics — page-level traffic statistics such as page views and referring site, used to understand which calculators are useful. This data is aggregate and is not linked to the values you enter.
• Advertising — this site may display advertising. Ad networks set cookies and may use them to serve interest-based ads. You can control this through your browser settings or the relevant industry opt-out programmes.

Cookies

No cookies are required for the calculators to function. If advertising is present, third-party ad networks may set cookies. Blocking cookies in your browser will not break any calculator on this site.

Children

This site is intended for a business audience and is not directed at children under 16.
