What you're buying

When you purchase a book from DeFi Books, you receive a personal, non-transferable license to one digital PDF copy of that book. The PDF is watermarked with your email address and order identifier on every page. The license is yours for life — your download link is valid for 30 days, and we'll re-issue it if you ask.

What you can't do

The license is for personal use only. You may not resell, share, redistribute, or post the file publicly. Removing or altering the watermark is not permitted.

Refunds

All sales are final once the watermarked PDF has been downloaded. Each PDF is generated specifically for you at the moment of purchase and stamped on every page with your email address and order identifier — there's no way to "return" a downloaded copy.

If your download link has not yet been accessed, you may request a refund within 7 days of purchase by replying to your delivery email. We track download status on every order and reserve the right to dispute chargebacks where the file has already been accessed.

If something genuinely went wrong with your order — corrupted file, wrong book delivered, payment problem — reply to your delivery email and we'll fix it.

Payments

Payments are processed by Stripe. Charges appear on your bank statement as PSIFI* DEFIBOOKS. We don't store or see your card details.
