Hi PortalPower,

As of right now, there is not a specific feature on the site to make programs private or unable to be seen by other users. Once you save your program, it will be able to be seen on your profile.

The best way to keep a program private is to create a separate child account and use that account to create the programs you would like to keep private. Due to the policies in place for accounts for users under 13, the program will only be seen if someone has a direct link to it. Instructions on creating a child account can be found here.

I hope this helps! Please let me know if you have any further questions.
