When the user utilizes the online license, KubiTarock synchronizes global settings, statistics, billing data, and cumulative results across multiple devices on which you log in with the same account. The program does this as follows:

• When logging in, the last backup date stored on the server is compared with the backup date stored on the device. Only if the date stored on the device is earlier will the server data be used in the user session. Otherwise, the data stored on the device remains unchanged.
• At the end of a user session, the user can use the “Save & close app” button to ensure that all data is uploaded. However, it is only stored on the server if the backup date stored on the server is earlier than the date stored on the device. On Android and iOS, this button should always be used to close the app, as all other termination options only perform a local backup. On Windows, however, the server backup is performed for all types of app terminations.

It is generally assumed that a user will only ever use KubiTarock on one device. If several users are active on the same account at the same time, only the data of the user who last saved and exited will be saved.
