Privacy

Updated October 19, 2026.

This storefront uses Cloudflare to serve the website, Bachs to process payments, and Resend to deliver your book. Bachs sends us the purchase details and the email address you provide at checkout. We use that address to fulfill your order and handle support.

The Worker does not receive your card details. Our optional quiz stores your answers as you go in Cloudflare D1, including unfinished responses, timestamps, progress, suggested result, and clicks through to checkout. A secure session cookie lets you return to your answers for up to 30 days. We retain responses until deleted; the cookie lifetime does not set the data retention period. We do not store raw IP addresses or browser fingerprints in survey records. If you voluntarily leave an email and give research permission, we store that permission and may contact you about your answers. This does not subscribe you to marketing or trigger automatic emails. Results do not require an email. Public statistics use grouped completed responses and exclude small categories. Only the password-protected dashboard can access individual responses. For deletion requests, contact us with your quiz session reference or the optional email you provided. Admin access uses a secure session cookie. Our service providers keep operational and transaction records under their own policies. Worker logs record event identifiers and processing status, not your email address or payment details.

This page has no advertising pixels, analytics scripts, newsletter signup, or tracking cookies. Cloudflare processes request information to operate and protect the service.
