What we collect

If you join the email list, we collect your email address. We use it to send you the free worksheets and occasional emails about money math and the book. That's all.

The calculators run entirely in your browser. Nothing you type into them is sent to us or stored.

Who processes it

Email addresses are stored with our email provider, MailerLite, which sends the emails on our behalf. The site is hosted by Vercel, which keeps standard server logs, such as IP addresses, to run and protect the service.

Your choices

Every email has a one-click unsubscribe link. To have your address deleted, email us at the contact address in any newsletter and we'll remove it.

Cookies

This site does not use advertising or tracking cookies.

Not financial advice

The book, the calculators and the emails are for education only and are not individualized financial, investment, tax or legal advice.
