eBook Access & Compatibility Policy

Last Updated: April 22, 2026

We want every customer to have a smooth and reliable experience with our digital products. This policy outlines what you can expect when purchasing and using PDF eBooks from our website.

Our Commitment

All PDF eBooks purchased on the Ener-Chi website are delivered in a widely supported, industry-standard format. Each file is reviewed to ensure it opens and functions correctly at the time of delivery.

If you experience any issues accessing your file, we are happy to help and can provide a replacement download if needed.

What We Guarantee

At the time of purchase, we guarantee that:

• Your PDF eBook file is complete and not corrupted
• The file matches the product description
• The file can be opened using standard, up-to-date PDF reading software

Accessibility

We aim to create PDF eBooks that are usable with common accessibility tools, including screen readers. However, accessibility performance can vary depending on the device, software, and individual user settings.

If you experience difficulty accessing your eBook, please contact us and we will make a reasonable effort to assist.

Compatibility Over Time

Digital formats and reading technologies evolve over time. While PDF is designed for long-term use and broad compatibility, we cannot guarantee compatibility with all future devices, operating systems, or screen reader technologies.

Compatibility depends on the software and tools available at the time of use, rather than the file itself.

Ongoing Support

We provide customer support for PDF eBooks purchased on the Ener-chi.com website for a period of three (3) years from the date of purchase.

During this time, we will make reasonable efforts to assist with access or compatibility issues, including providing replacement files or guidance when available.

After this period, support may be limited. We may still offer assistance at our discretion, but cannot guarantee availability due to changes in technology and software over time.
