Chroma Profiles Backup - Synapse doesn't launch

Synapse all of a sudden stopped working, I can see all its processes running in the task manager but the program never actually launch. Before I re-install it I need to perform a backup of at least the chroma profiles, as I worked hours on them and there are quite a few.
Where can I find these files? are they available in my pc without accessing Synapse?
(the profiles are for a Mamba Elite, if that is useful to know)
