If you want the real web version then you need to register in their website and create a team first. Yes, KaDeck is aimed at teams of people working together. You create a team online and shortly you receive a mail with team id and a secret key that you will use when running KaDeck web..
It seems that there is no host installation of KaDeck right now (rpm package, binaries or so) but only a Docker image. This forces the user to run it in Docker or a Kubernetes cluster (or one of it’s commercial distributions such as OpenShift). Another thing is that checks your license online each time you start the container. If you want to use t offline you have to do a process of offline activation. You can reach it from the administration menu.
