We use Amazon Web Services (AWS) to store your data. AWS stores data for many companies like Centriq and provides industry standard data protection and backup services. You can read more about it on our website at https://www.centriqhome.com/privacy/#howweprotectyourinformation
Since it is "in the cloud", if you lose your phone or if you don't have enough space, your account and it's contents are not locally stored and you still have access to it from anywhere.
Along the same lines, your account gives you access to the same information across devices, so you can access it on multiple phones, across Android and iPhone, and on iPad. If you want to share information with someone else, use one account and log in to that account on your separate devices.
Please contact us at firstname.lastname@example.org if you need more guidance, have questions, would like to submit a feature request or if you have other feedback.
Don't forget that you can access Centriq Online to use Centriq on your laptop or desktop computer or for optimized use on tablets.
