Privacy Policy
Last updated November 14, 2026
We collect only what we need to deliver your order and serve you as a reader.
What we collect
- Order details: name, mailing address, email and (if you give it) phone number, so we can ship your book, send receipts and contact you about your order.
- Payment details: processed by our payment processor. We do not store your full card number.
- Tool inputs: numbers you enter in our calculators are processed in your browser to produce your estimate.
- Site usage: standard analytics and advertising measurement (for example, which ad brought you here), using cookies or similar technology.
How we use it
To fulfill orders, provide members-only content, send the emails you signed up for, answer questions, prevent fraud and improve our publications. You can unsubscribe from marketing emails at any time using the link in any email.
What we never do
We never sell your Social Security number, because we never ask for it. We never ask for your bank account information, your my Social Security password, or your Medicare number.
Sharing
We share information only with service providers who help us run the business (payment processing, printing and shipping, email delivery, hosting, analytics), when the law requires it, or with your clear permission.
Your choices
You may ask us to access, correct or delete your personal information by visiting our Contact page. Residents of some states have additional rights, which we honor.
Children
Our site is intended for adults.
