After Stripe verifies payment, the site emails a private download link to the checkout address. A verified success page may also offer an immediate 15-minute link.

Email links expire after 72 hours. Expiration does not end an active license: use the download-recovery page to request fresh links. Links are signed, order-specific, and checked against payment and refund state every time they are used.

Download files are ZIP archives. Save the archive locally, scan it with current security software, extract it, and open PDFs in a current PDF reader and EPUBs in a compatible reading app.
