Can I keep all offers?

Hello,

I have received a conditional acceptance from UvAmsterdam, and my next step is to confirm my participation within seven days. The message also states that the decision is not binding.

I have also received a conditional offer from the University of Groningen. If I confirm participation with UvAmsterdam (even though it is described as non-binding), will other universities be notified of this confirmation? Could this affect my application process with other institutions?
