Your calculations
Calculations normally run in your browser. Inputs also appear in the page address so a link can restore the calculation. Anyone you send that link to can see its values, and the address can appear in your browser history.
Opening or reloading a link sends its address, including any inputs in it, to Cloudflare, our hosting provider. For some calculators, our server uses those inputs to generate a personal title and sharing image. These previews are cached by Cloudflare. Names or other personal information included in a link become part of that request and may appear in hosting logs.
Cookies and storage
We don’t set cookies. If you pick a region or switch between light and dark mode, your choice is saved in your browser’s local storage so the site remembers it. These preferences stay in your browser.
Analytics
Application-level analytics are currently off. Hosting still processes the technical requests described below.
Hosting
The site is served by Cloudflare. Like any web host, Cloudflare processes technical data such as your IP address to deliver the page and protect it from abuse. See Cloudflare’s privacy policy.
When you contact us
