If you don't trust Dianne (although I recommend you to do so) you could set the needed permissions for that file yourself (if you have root access).
If you don't have root access you might want to use a database (apps can't access another's app database) or encrypt your files using a magical encryption mechanism. I think there are tons of solutions for something like that out there. One more thing: If the data you want to protect is REALLY important, the only secure solution would be an encrypted file. Any app with root access could read your file if you use one of the other techniques mentioned.
