This page explains how digital purchases are delivered, how customers can access their files and what to do if a delivery problem occurs.
How Digital Delivery Works
CISAGO digital products are delivered electronically.
After a successful purchase, customers receive access to their product through the delivery method shown during checkout.
Depending on the product and payment system used, delivery may include:

- Another clearly stated digital delivery method
No physical shipment is required for digital products.
Delivery After Payment
Digital access is normally provided after payment has been successfully authorized or completed.
In most cases, delivery is available shortly after checkout.
Occasionally, payment verification, fraud prevention checks or technical processing may delay access.
If your payment has been completed but you have not received your product, please check your email and order information before contacting support.
Please Use a Valid Email Address
Customers are responsible for providing a valid and accessible email address during checkout.
Important delivery information may be sent to the email address associated with your order.
Before contacting support, please check:
- Your inbox
- Spam or junk folders
- Promotions or filtered folders
- Whether the email address used during checkout was entered correctly
eBook Delivery
CISAGO eBooks may be provided in formats such as:
PDF files can generally be opened on computers, tablets and smartphones using compatible PDF-reading software.
EPUB
EPUB files are designed for compatible eReaders and reading applications.
The specific format included with each product is displayed on the relevant product page.
Customers should confirm that their preferred device or application supports the selected file format before purchasing.
Audiobook Delivery
CISAGO audiobooks are delivered digitally.
Depending on the title, customers may receive:
- Downloadable audio files
- A secure file-access link
- Multiple chapter files
- Another clearly described digital audio delivery format
Where an audiobook consists of multiple files, the customer may receive access to the complete set through a single delivery page or secure folder.
The exact delivery method will be stated where relevant.
Download Links
Download links are intended only for the customer who purchased the product.
Customers should not publish, share, resell or distribute download links.
For security and system-protection purposes, download links may:
- Expire after a period of time
- Be limited to a reasonable number of downloads
- Be replaced if suspicious activity is detected
If you are the legitimate purchaser and can no longer access your product, please contact us with your order details.
Secure File Access
Some CISAGO products may be delivered through a secure third-party file-hosting or digital-delivery service.
In such cases, customers may receive a private access link rather than an email attachment.
Access links are provided for the purchaser’s personal use and remain subject to the applicable CISAGO licence terms.
What If My Download Does Not Work?
If a download link fails or a supplied file cannot be opened, please first try the following:
- Confirm that your internet connection is working
- Try downloading the file again
- Try another compatible browser
- Confirm that your device has enough available storage
- Confirm that you are using software compatible with the supplied file format
If the problem continues, contact CISAGO support.
Please include:
- Your full name
- Order number
- Purchase email address
- Product title
- A description of the problem
Where appropriate, we will provide renewed access, a replacement file or another reasonable solution.
Corrupted or Incomplete Files
If a file supplied by CISAGO is corrupted, incomplete or technically unusable, please contact us.
Once the problem is verified, we will make reasonable efforts to provide a working replacement or restore access.
Device Compatibility
Digital file compatibility depends on the device, operating system and software used by the customer.
CISAGO cannot guarantee compatibility with every third-party device, application or eReader.
The product format will be stated before purchase wherever applicable.
Customers are encouraged to verify compatibility before ordering.
Internet and Data Costs
Customers are responsible for their own internet connection and any data, mobile network or third-party software costs associated with downloading or accessing CISAGO digital products.

Unless otherwise stated, digital purchases are licensed for the personal use of the purchaser.
Purchasing a product does not transfer copyright or ownership of the underlying intellectual property.
Customers may not:
- Redistribute purchased files
- Upload them to public file-sharing services
- Share private download links
- Resell copies
- Repackage the content
- Make the content publicly available
- Use the material commercially without permission
Please see our Rights & Licensing page for further information.
Lost Files
Customers are encouraged to keep a secure personal backup of legally purchased files where the supplied format permits this.
If you lose a downloaded file, we may be able to restore access where the original purchase can be verified.
Permanent re-download availability is not guaranteed unless explicitly stated.
Payment Providers and Digital Delivery Partners
CISAGO may use third-party payment processors, merchants of record, file-hosting providers or digital-delivery services to process transactions and deliver digital products.
Where a third-party provider is involved, some purchase, payment and delivery information may also be processed in accordance with that provider’s terms and privacy practices.

Please review that policy for further information about refund eligibility.
