Do I need to install anything to use Kluppy?
No. Kluppy works directly in the browser: you go to play.kluppy.com, log in, and start. There is no program to download, no plugin, and no updates to manage. Every time you log in, you are already on the latest version.
The only thing you need is a computer with a physical keyboard and an internet connection.
In an educational center, you don’t have to install anything on the computers or ask for administrator permissions: it is enough for the computers to be able to open play.kluppy.com from the browser.
