License Types

There are 3 types of Duplicacy licenses:

The CLI version is free for personal use. In addition, if the operation is to restore or manage existing backups (such as check, copy, and prune), the CLI version can be run by anyone on any computer without a CLI license.

All licenses are subscription-based. Latest releases and upgrades are available at no extra charges during the subscription period.

One GUI license, Commercial or Personal, can be installed on one computer. If you need to run the GUI version on multiple computers, one license is required for each computer.

License Exceptions

GUI/CLI licenses are not required under the following situations:

You can use the personal GUI license to back up any files if you are a student, or a staff/faculty member at a school or university.


Will my licenses get renewed automatically?

We don't renew your licenses automatically. Instead you pay a one-time fee based on the number and length of the licenses. You can always renew a license (at the rate for subsequent years) before or after it expires. We'll send you a reminder about 7 days before your licenses expire.

How do I receive my purchased GUI/CLI licenses?

After placing the order, you will receive a number of License Activation Codes. For GUI licenses, you can then enter one license activation code in the activation dialog for each computer. Duplicacy will then download the license from our license server and save it to the registry on Windows or the user defaults on Mac.

CLI licenses, however, do not need to be activated, as the CLI version doesn't not have a license checking mechanism.

My GUI license became invalid after I upgraded my computer and reinstalled OS. How do I restore the license?

Just enter the same license activation code in the activation dialog and Duplicacy will re-download the license from our license server.

Please note that the GUI license is bound to the host name. So if the host name ever changes, you will need to set the new host name on the licenses page and then activate with the same activation code.

I activated my GUI license on my laptop but now I want to use it on my desktop. How do I transfer the license?

Go to the licenses page and change the host name associated with the license activation code. Then enter the same license activation code in the activation dialog when Duplicacy runs.

If you don't change the host name first, Duplicacy won't activate the GUI license even if you enter the right license activation code.

Is it safe to use my credit card on

Our license server simply passes your credit card information directly to our payment processor, We do not save your credit card anywhere in our system.

In addition, the connections between your web browser and, between your web browser and our license server, between our license server and, are all securely encrypted.

Alternatively, you can use paypal to purchase licenses.

Can I get a refund if I find out Duplicacy isn't the right tool for me

Absolutely. Just email us any time and we will issue a refund proportional to the unused portion of your subscription. When you do so, please let us know why you are not satisfied and what you think we can do to make Duplicacy better.

I bought a personal license before and I want to buy more. How do I get the discounted prices for additional personal licenses?

Enter any license code from your previous licenses as the promotional code and the discount will apply automatically.

I work for a non-for-profit organization/government agency/school/university. Can I use a personal GUI license for work?

A personal GUI license is meant to be used at home not related to employment. So the answer is generally no.

However, we would like to make an exception for schools and universities. If you are a student, or a staff/faculty member at a school or university and have purchased a personal GUI license, you can use it to back up any files, not just those on your home computers.
