You can create a sub-account for kids using the Group Admin feature. You can set the user type to Regular Member. 
                                Your kids can log on with their sub-account's username and password. By default, they cannot access your files.
                                
                                DriveHQ supports 4 types of subusers: Group Admin, Subgroup Admin, Regular Member and Guest User. 
                                For Personal (and free) plans, you can only create one sub-account. You can use the sub-account for sharing files
                                with other people.
                                
                                After you create the sub-account, 
                               you can create folders in your own My Storage and share them with the subuser and set different permissions. 
                                The sub-user can only
                                see folders shared with him/her.
