Privacy Policy
Last updated October 31, 2026.
CalcArcade is designed to collect as little as possible.
Your calculator inputs
All calculations run in your browser. The numbers and dates you type into a calculator are not sent to our servers and are not stored.
Saved on your device
If you use the favorites button, the site remembers which calculators you saved and the last few you opened, in your browser's local storage. The first time you visit, the site reads your browser's language setting on your device to pick starting units and a currency symbol (it is not sent anywhere or stored). If you pick a currency or unit setting yourself, that choice is stored the same way. This stays on your device, is never sent to us, and holds no calculator inputs. Clear your browser's site data to remove it.
Calculators embedded on other sites
If a website embeds one of our calculators, what a visitor types still stays in that visitor's browser: it is not sent to us, we set no cookies, and nothing is stored. The site that embeds the calculator is separate from us and may have its own privacy practices.
Cookies and tracking
This site does not currently set cookies or run advertising or analytics scripts. If we add analytics or advertising in future, we will update this policy first and show any consent choices the law requires.
Server logs
Like any website, our hosting provider may keep standard server logs (such as IP address, browser type and the pages requested) for security and reliability.
If you email us, we use your message and address only to reply and to improve the site.
