Prohibit source code downloading

[Fruit Punch Samurai G]

Hello. I have ran into a problem and I really need help. Here's the situation:

We have a client who insists on using their own Google account for App Engine. However, we don't want them to be able to see or download the source code that we uploaded. We are using a flexible environment and are using Golang. Is there any way to prevent them from download or viewing the code even if they are the ones holding the Google account? Please help.

Hi, 

In order to have an user being able to view applications versions and instances and also be able to monitor their performance without being able to view the source code you would need to give them one of the predefined roles except for App Engine Code Viewer.

However if your client already has the project owner role they will by default have the permissions to see and download the source code.
