Teachme Biz uses Amazon Web Service (AWS) as its data center.
A shared responsibility model is applied between AWS and our company, and security responsibilities in cloud service provision are shared between AWS and our company.
For example, AWS is responsible for operating and managing the physical security of the facilities where the service operates, while our company is responsible for the applications running on top of it and security settings, etc.
For details on AWS's shared responsibility model, please refer to the following document:

We have confirmed that the above shared responsibility model can fulfill the requirements of our terms of service, and have concluded a contract.
