The {{UBIK}} client gets its data from the UBIK Content web service and is capable of synchronizing differences between this service and itself.
All data can be worked with offline.
Depending on the [[Sync Mode]] setting, the synchronization will behave differently - either taking care of everything automatically or giving the user full control over which changes are sent ("committed") to the server and which updates are fetched from it.
In case of an error, an Android Notification is shown to gently notify the user what has happened and eventually give hints on how to solve the problem.
