Under the deal, MacPaw will continue to support The Unarchiver and its family of apps with updates and localised languages as well as making improvements to the design. The app will remain free, the company added.
Dag Ågren, the developer of The Unarchiver first developed the software over ten years ago.
“[Ten] years is a very long time to work on the same project, and due to other factors in my life, I've had less and less time to actually work on them,” said Ågren.
“I have felt bad about not maintaining and updating them properly. Therefore, I felt it is time to hand the flag over to someone else who can take care of them properly, and make sure they stay around for a long time still,” he added.
“It’s a big honour for us to keep the product alive for the users,” said Oleksandr Kosovan, CEO of MacPaw, which is behind the Setapp software.
The Kiev-based company, which also has a presence in California, recently sold off its DevMate app development platform to UK company Paddle.
