4. How we operate

Digital Shelf Lab designs, produces and sells affordable digital products — such as ebooks, collections, templates, guides and simple apps — priced in US dollars (in some countries, prices are shown and charged in your local currency). On Stiffwell, card payments are processed by Stripe, a PCI-DSS compliant payment provider; we never see or store your full card number. Charges appear on your card statement as "DSL* STIFFWELL". Stiffwell sells a routine app that runs in your phone's browser and PDF guides: after payment, we email you a link to your personal access page, where you can open the app and download your files. We do not ship physical products.
