Privacy Policy

Last updated: October 26, 2026

The short version

• Our tools run in your browser. The measurements you type and the files you download are not sent to us or stored on our servers.
• We don't ask for your name, email or an account.
• We use Google Analytics to count visits and see which features people use, so we can improve the tools.

What we collect

Google Analytics collects usage data such as pages viewed, approximate location (country or city), device and browser type, and how you arrived at the site. We also record a few anonymous events inside the tools, for example when a template is downloaded, which format was chosen, and which preset was used. These events don't include anything that identifies you.

Google Analytics uses cookies to tell visits apart. You can block or delete cookies in your browser settings, or install the Google Analytics opt-out add-on. Learn how Google uses this data at How Google uses information from sites that use its services.

Hosting

The site is hosted on Cloudflare. Like any web host, Cloudflare processes technical data such as IP addresses to deliver pages and protect the site from abuse. See the Cloudflare Privacy Policy.

Links in shared URLs

Tool settings are saved in the page address so you can bookmark or share a result. Anyone you send that link to will see the same measurements.

Children

The site is not directed to children under 13, and we don't knowingly collect information from them.

Changes

If we add advertising or change how we use data, we will update this page and the date above.
