What information Checked Math processes when you use a calculator, what it never asks for, and how changes to this policy are announced.
- Last updated
Calculator inputs
You do not need an account to use any calculator. The numbers you type stay in the page in your browser, are calculated there, and are not sent to a server, saved to browser storage or written to a database by this site.
The hosting service that delivers the site may process standard request information such as IP address, browser user agent, requested page, time and security-related data in order to deliver and protect the service.
Analytics and advertising
The site does not run analytics, tracking or advertising scripts. If either is ever added, this policy will name the service, what it collects and why, and any consent choice it requires will be in place before it runs.
Keeping personal information out
- Do not enter passwords, account numbers or other secrets into calculator fields — no calculator needs them.
- Calculators only ask for numbers and units; there are no free-text fields for personal details.
Changes to this policy
A material change to how information is processed is described on this page and the “Last updated” date above changes with it.
