Privacy Policy

Effective October 5, 2026

The short version

The calculators run entirely in your browser. Data you type or paste into them is never sent to us or stored on a server. We collect only what's described below.

Calculator data

All calculations happen locally in your web browser. The 5 Whys tool saves your draft in your browser's local storage so a refresh doesn't lose your work; that draft stays on your device, and you can delete it with the tool's "Start over" button or by clearing your browser data.

Contact form

If you use the contact form, we receive the name, email address, and message you submit. We use it only to reply to you and don't sell or share it. Form submissions are processed by our hosting provider, Netlify.

Hosting and server logs

The site is hosted by Netlify, which may automatically log technical information such as IP address, browser type, and pages requested in order to deliver and secure the site. See Netlify's privacy policy.
