If you are a multi-tenant Cloud customer then your data is stored in a separate database(s) that is not shared with any other client, but that database is on a server that is shared with other Clients. We do not allow clients any direct access to our multi-tenant Cloud servers. Your databases are also secured to only allow access to your users. (If you are a single tenant Cloud, or Premise Customer then only you and your Fitrix team have access to your Fitrix server).
