Information you enter into calculators
The numbers you type into a calculator are processed in your browser to show the result. We do not send them to our servers and we do not store them.
Information we collect automatically
Like most websites, our hosting provider and analytics tools may record technical information such as your IP address, browser type, device type, pages visited, referring page and the date and time of your visit. We use this to keep the site secure, understand which tools are useful and fix problems.
Local storage
If you switch between light and dark mode, your choice is saved in your browser's local storage on your device so the site can remember it. It is not sent to us.
