The short version
Our calculators run entirely in your web browser. The numbers you type in are never sent to our server or stored by us.
What we collect
- Calculator inputs: not collected. They stay on your device.
- Server logs: like most websites, our web host records technical information such as IP address, browser and pages requested, for security and to keep the site running.
- Emails you send us: if you contact us, we keep your message and address only to reply and handle your request.
- Display preferences: if you change the text size, colours or other options in the Display panel, your browser stores them in its local storage on your device. They are not sent to us.
