All data is held on servers based in regional data centers managed by Microsoft Azure. Xperios also holds a local copy of your data in an encrypted format on your device and keeps this in sync with your master database.  

This provides two advantages. Firstly, it means that Xperios is super fast at looking up and displaying data. Secondly, it allows you to access Xperios in “Read Only” mode when you are not connected to the internet. 

Please note, you need to be connected to the internet to make changes to your data. Any changes made are to both the master database and your local copy.
