Skyvia stores backed up data in secure Azure GRS storage. All your data is stored in an encrypted form, and our engineers don't have access to it. They only have access to your packages metadata.
All the interactions of our UI with API are encrypted with SSL, so you don't need to worry about security of your data. Since Skyvia is hosted in the Windows Azure cloud, so all the latest security updates are always applied.
Geographically, backed up data are stored in West US data centers.
