Will the code be deleted when I close vscode-go:playground?

I accidentally clicked on "go run on go playground" when I was developing in vscode. Since it is a company code, I would like to know if the code will be deleted.

You can't delete the code yourself, but as mentioned in this google groups thread, you can contact Russ Cox or security@golang.org and ask to delete the code. But as long as you don't share the link, nobody should be able to see that code similar to YouTube's unlisted videos feature.
