Privacy Policy

Last updated: October 12, 2026

What we collect

  • Email address — when you join the launch list, request a review copy, or place an order. Used to send order confirmations, deliver digital products, and (only if you opted in) launch updates.
  • Order details — the product you bought, the amount, and your transaction reference. Kept as an order record.
  • Messages you send us — errata reports, support requests, and contact-form submissions, so we can reply.

Payment processing

Payments are processed by Stripe. We never see or store your full card number. Stripe handles card data under its own PCI-compliant infrastructure; we receive only a confirmation of payment and your billing email.

What we do not collect

We do not run third-party advertising trackers on this site. Reader experiment data generated by the interactive panels stays in your browser's local storage and is never sent to our servers.

How long we keep it

Order records are kept for as long as needed to deliver what you bought and to meet legal or tax obligations. Launch-list emails are kept until you unsubscribe.

Your choices

You can unsubscribe from launch updates using the link in any update email. To request access to, correction of, or deletion of your data, contact us.

Every claim is measured, simulated, or honestly labeled.

Continuum Press

We publish engineering truth. Every claim is testable. Every simulation is reproducible. Every correction is visible. Every hypothesis can lose. This is how engineering should be taught. This is how engineering should be published.
