F-Secure KEY (http://www.f-secure.com/en/web/home_global/key) is using secure server in Finland for data synchronization across all devices. Can we use/buy our own local server for data synchronization for our users?
We're not currently planning to license the synchronization server. I can see use cases where you might want to do that, but ensuring the protocol compatibility between the apps and the server in a heterogenic environment could be tricky. Hence we offer the sync currently only as a service.
