Hi, thanks for reaching out!
Datalore Enterprise is a self-hosted version of Datalore that you install on your companies infrastructure (in private cloud or on on-premise servers). JetBrains doesn’t have any access to your data when you work within Datalore Enterprise. The checkbox you are mentioning doesn’t exist in the Enterprise version.
Also, Datalore Professional is an individual subscription that is not available for companies yet.
So the Enterprise version is the way to go to ensure that data doesn’t leave your company’s environment.
