Protecting your data (and your script)
We have seen in the previous section how to prevent an unauthorized user from accessing your web apps. However, in some cases, we would like to allow users to use the application, but not to be able to modify our script (even accidentally) or open a script-related document.
With reference to the first point, we should clarify again some aspects of file sharing and app sharing to be sure that there is no ambiguity in your understanding of the concepts:
In standalone apps, the script doesn't need to be shared for a user to run the app (but, in spreadsheet- or document-embedded scripts, the permissions for the script are the same as those for the container).
If an app is running on the User accessing the web app option, each file for which the script can read or write must be shared with that user too (or be public or shared with Anyone with the link).
Note that the code itself doesn't need to be shared for an app to be shared. Don't share your code if it...
