Refund Policy

Epubor values every customer and strives to provide a positive experience with our products and services. Epubor software is offered on a "try-before-you-buy" basis whenever a trial version is available. We strongly recommend that you download and try the software before purchasing to make sure it meets your requirements and is compatible with your system.

Refund requests are generally eligible within the applicable refund period, subject to the conditions below.

Standard licenses: Refund requests must be submitted within 30 days of the initial payment date.

1-Month licenses: Refund requests must be submitted within 7 days of the initial payment date.

After the applicable refund period has expired, we generally do not provide refunds solely because of changes in software compatibility, third-party platforms, operating systems, hardware, or security technologies.

Examples include, but are not limited to:

Because Epubor software may depend on third-party platforms and technologies, compatibility with every future system, device, application, file format, or security mechanism cannot be guaranteed.

We will make reasonable efforts to maintain compatibility with supported platforms and release updates when technically feasible. However, technical changes introduced by third parties may affect the functionality of Epubor software and may require substantial development work or may not be technically recoverable.

These compatibility changes do not, by themselves, constitute the expiration or cancellation of a Lifetime License and are generally not grounds for a refund after the applicable refund period has expired.

To request a refund, please follow the steps below.

Step 1: Run Epubor software and click "Settings" >> "Tools" >> "License Manager" >> "De-Register".

Step 2: Send an email to support@epubor.com with the following information:
1. Your order number or purchase email address
2. The reason for your refund request.

Once we receive your request, our customer support team will review it and get back to you within 48 business hours.

 

Single-User License

A Single-User Personal License may be activated on up to two personal computers owned or controlled by the license holder. However, the software may be used on only one computer at a time.

The license is intended for personal use by the original purchaser and may not be shared with or transferred to another person.

1-Month License: The license is valid for one month from the date of purchase. During the applicable license period, you may contact Epubor Support for technical assistance and receive eligible software updates.

1-Year License: The license is valid for one year from the date of purchase. During the applicable license period, you may contact Epubor Support for technical assistance and receive eligible software updates.

Lifetime License: A Lifetime License does not have a fixed expiration date. During the applicable license period, you may contact Epubor Support for technical assistance and receive eligible software updates, subject to the supported platforms, system requirements, and terms described on this page.

Important: A Lifetime License refers to the duration of the license and does not guarantee perpetual compatibility with every future operating system, computer, device, third-party application, ebook or audiobook platform, file format, or DRM/security technology.

 

Multi-User Licenses

A Multi-User License is intended for use by the specified number of authorized users or computers within a family, organization, or corporation, according to the license purchased.

Family License: A Family License may be used on the specified number of computers (typically 2-5 computers) according to the purchased license terms. During the applicable license period, users may contact Epubor Support for technical assistance and receive eligible software updates.

Pricing for multi-user licenses depends on the number of authorized users. The more users, the lower the per-user price may be. If you intend to purchase a large number of licenses, please contact Epubor Support for a customized quotation.

 

Extended Download Service

Our Extended Download Service helps customers access their registration information and supported software downloads when they need to reinstall purchased software.

The Extended Download Service is currently provided free of charge. During your applicable license period, we will make reasonable efforts to maintain access to your registration information and supported software download links.

If your computer experiences a system crash, hard drive failure, or similar issue, you can use the service to reinstall supported versions of your purchased software, subject to availability.

 

As Our Client, You Can:

During your applicable license period, you may use the purchased software in accordance with the license terms and supported system requirements.

1. Contact Epubor Support for technical assistance regarding supported versions of the software.

2. Download supported versions of your purchased software when available.

3. Receive eligible software updates released during your applicable license period.

4. Transfer or reactivate your license when changing computers, subject to the applicable license terms and compatibility requirements.

5. Request a license change or upgrade when an applicable upgrade option is available.

Please note: Software updates and technical support do not guarantee compatibility with every future operating system, device, hardware architecture, third-party application, ebook or audiobook platform, or DRM/security technology.

 

License Change / Upgrade

From Mac to PC or from PC to Mac: A license purchased for one operating system or platform may not be used on another platform due to differences in the software architecture. Please make sure you select the correct operating system when purchasing.

If your order is still within the applicable refund period (30 days for standard licenses and 7 days for 1-Month licenses), you may purchase the correct platform version first and then contact Epubor Support regarding the original purchase.

Changing from an old computer to a new computer: If you replace your computer with another computer using a supported operating system and platform, you may contact Epubor Support to transfer or reactivate your license.

For example, if you purchased a 2-Year License and used it for one year before your computer became unusable, we can help transfer the remaining license period to another supported computer. The previous activation may be deactivated when the license is transferred.

Important: A license transfer or reactivation does not guarantee that the new computer will be compatible with the software. Compatibility may vary depending on the operating system version, hardware architecture, device configuration, and third-party applications installed on the computer.

Hardware Architecture Changes: Different hardware architectures may have different compatibility requirements. For example, Intel-based Macs and Apple Silicon Macs may require different software versions or technical implementations. Moving from one hardware architecture to another does not automatically guarantee compatibility.

Upgrade from a Basic Software to a More Comprehensive Software: If you have previously purchased one of our products and wish to upgrade to a more comprehensive product, you may be eligible to pay only the applicable price difference or upgrade fee. Upgrade eligibility and pricing depend on the products involved.

Upgrade from a Limited-Period License to a Lifetime License: If you have purchased a limited-period license, you may be eligible to upgrade to a Lifetime License. The applicable upgrade price depends on the software purchased and the available upgrade program.

For license changes and upgrades, you may be required to provide your purchase email address, transaction number, and name. Once we verify your purchase record in our database, we can process the applicable license change or upgrade.

 

Software Compatibility and Future Updates

Epubor software is designed to work with supported operating systems, devices, ebook and audiobook platforms, file formats, and third-party applications. Because these technologies are continuously evolving, compatibility may be affected by changes made by third-party companies, operating system vendors, device manufacturers, platform providers, or security technology providers.

A Lifetime License grants a lifetime license term; it does not guarantee perpetual compatibility.

A Lifetime License does not guarantee that the software will remain compatible with every future version of Windows or macOS, every hardware architecture, every device, every third-party application, every ebook or audiobook platform, every file format, or every future DRM or security technology.

We will make reasonable efforts to maintain and improve compatibility with supported platforms and release updates when technically feasible. However, certain changes introduced by third parties may require substantial technical changes, may temporarily affect functionality, or may make continued support technically impractical.

Examples of changes that may affect compatibility include:

Before purchasing, we recommend that customers use the available trial version and review the current system requirements to confirm that the software meets their needs.

 

Understanding the Lifetime License

What does "Lifetime License" mean?

A Lifetime License means that the license does not have a predefined expiration date, subject to the applicable license terms. It allows you to continue using supported versions of the purchased software without purchasing a recurring subscription.

Lifetime does not mean that every future version of the software, operating system, device, platform, or third-party technology will remain compatible.

Because Epubor products may interact with third-party ebook and audiobook platforms, DRM technologies, operating systems, and applications, changes outside Epubor's control may affect software functionality.

We continuously work to maintain compatibility with supported platforms and provide updates when technically feasible. However, we cannot guarantee that all current features will remain available under every future technical environment.

In the event that a third-party platform or technology changes, Epubor may provide an updated version, workaround, or other technical solution when reasonably possible. The availability of such a solution depends on the nature and feasibility of the underlying technical changes.

 

Frequently Asked Questions

Does a Lifetime License guarantee lifetime compatibility?

No. A Lifetime License refers to the duration of the license, not a guarantee that the software will remain compatible with every future operating system, computer, device, third-party application, ebook or audiobook platform, file format, or DRM/security technology.

My computer stopped working with Epubor software. Can I get a refund?

If the applicable refund period has expired, incompatibility caused by a change in operating system, hardware, hardware architecture, third-party application, ebook/audiobook platform, or security technology generally does not qualify for a refund.

If you have changed computers, please contact Epubor Support first. We will check whether a compatible version or another technical solution is available for your system.

Does Lifetime License mean I will receive every future version for free?

A Lifetime License includes eligible software updates released during the applicable license period. However, compatibility with future operating systems, hardware architectures, third-party applications, platforms, and security technologies cannot be guaranteed.

What happens if Kindle, Kobo, Audible, Adobe, or another platform changes its security technology?

Third-party platforms may change their DRM, security mechanisms, file formats, authentication systems, or download methods without notice. Such changes may affect Epubor software functionality.

We will make reasonable efforts to investigate and address compatibility issues when technically feasible. However, we cannot guarantee that every third-party platform change can be supported immediately or permanently.

What if I switch from an Intel Mac to an Apple Silicon Mac?

Intel-based Macs and Apple Silicon Macs use different hardware architectures and may have different software compatibility requirements. If you switch to a different hardware architecture, please contact Epubor Support to reactivate or transfer your license and check the currently supported software version.

What if a future macOS or Windows update makes my current version incompatible?

Operating system vendors may introduce changes that affect software compatibility. We will make reasonable efforts to maintain compatibility with supported operating systems, but we cannot guarantee that every future operating system version will be compatible with every existing version of Epubor software.

Can I use my Lifetime License on a new computer?

Yes, subject to the applicable license terms. If you replace your computer, please contact Epubor Support for license transfer or reactivation. The new computer must meet the current system requirements and use a supported platform.
