Hi Jeff Yu,

If you choose No for Enable online services, the app will only be stored on your local disk.

You can later upload the app to a version control server. 

You can also work with an on-premises version control server. To do this, you can: 

1.Click New App on the My Apps page 

2.In the App Settings dialog box, click No for Enable online services 

3.Go to Edit > Preferences > Advanced in the top menu of Studio Pro 

4.Make sure the Enable private version control box is checked 

5.Select Version Control > Upload to Version Control Server in the top menu 

6.Select Private server in the Upload to Version Control Server dialog box 

7.Enter the address of your SVN server in the App repository address field
