Where are the halion clock:it go backend servers operated?

We work with a certified German IT provider that operates two of its own data centers in Frankfurt am Main. Both data centers are certified according to current standards and are subject to regular audits. With the exception of the provision of the app via the store pages of the respective providers (Apple, Google), we do not use public cloud services such as AWS or Azure, but operate our own servers at our provider. This gives us complete control over the communication channels and the handling of the data.
