Force mod on folder

[JakeR]

Hi

I have a folder where an application saves files. The application runs mod 600 on all the files it saves. The application runs as a different user. This is my problem.

I want to give my user access to the folder and files.

Can I do anything to force the settings on the folder (for example deny permission changes)? The application always overrides my settings. I've tried with ACL, such as:
setfacl -m g:app:rwx,d:g:app:rwx,g:jake:rwx,d:g:jake:rwx /path/to/folder

Is it the application that is doing that? Or is it the user (i.e. umask)?
If the application itself is doing this, then that application is most likely misbehaving. In some cases, however, such as encryption key generators, it is appropriate to restrict access to the file to its actual owner.

What application is it?
