What is a personal watermark?

Every PDF you purchase will have a watermark containing your name, email, and order code in the footer of every page. This allows us to trace any leaked files back to the original account. The watermark does not obstruct reading — you can still read, print for personal use, and save permanently to your device.

Refunds: when are they possible?

Refunds can be requested within 7 days of purchase, and only for technical reasons:

• PDF file is broken / cannot be opened in a standard reader (Adobe Reader, Chrome, etc.)
• Blank pages or corruption after download
• Accidental purchase (double-click, etc.) — report within 24 hours

Refunds are not given because: you don't like the book's content, you already downloaded it, or other subjective reasons. Use the free preview before purchasing.

Download link not working / expired

Download links are valid for 30 days from purchase, with a maximum of 5 downloads. After that the link expires — contact us via email with your order code to reset it.
