Terms and Conditions

Due to the non-returnable nature of digital downloads, all sales are final.



Please note that the download links expire after five download attempts or 120 hours after being issued (whichever comes first). The email that contains the download link may go into your Spam or Junk Mail folder. Please email sales@lingualism.com if you do not receive an email within 10 minutes of successful payment, or if there are any problems downloading any files after you have completed payment. Also, please be sure to save the downloaded file in multiple locations on your computer to protect against accidental deletion of the file.

Personal use

When you purchase an ebook, that copy is intended for your own personal use. While you can copy an ebook file for use on another device you own, such as a tablet or smartphone, you cannot share copies with other people. You also cannot sell used ebooks; ownership is yours only, and cannot be transferred.
