What we collect
When you buy an e-book, we collect the email address and billing details needed to process your order and deliver your download. If you contact us directly, we keep the information you provide so we can reply.
Payment
Payments are processed by Stripe. We never see or store your card details — they go directly to Stripe’s own secure systems.
