Every client is automatically saved on your smartphone. However, only the clients which are synchronized to the Cloud will additionally be saved on the Cloud server. You can see if your contacts are on the cloud server when the cloud icon is displayed to the right of the contact in the contact overview. This means that if your clients are not synced to the Cloud, when you choose to uninstall the app, the clients that are only saved on the smartphone will be lost the moment you uninstall the HealAdvisor Analyse app. They are not lost if they were synced to the Cloud, because you can download them again when you login into the app and press the “Sync changes” button. If you are using the app with another device and have deactivated synchronisation to the cloud on the initial device, your clients cannot be displayed on the second device.
