I've had a few questions about security so I'll post this here for everyone.
Privacy statement for the app:

At no time do I have access to your password, nor will I ever put a feature in that would require me to have it. The app logs directly into RPoL and pulls your feed url from your preferences. The only thing I can see is your feed's URL, your username, the GCM ID (a Google code specific to your install of the app). Lastly your last fetched feed is saved so it can be compared to the new version for changes.
Basically, if I where for some reason to get curious, I could pull a list of games you play in. That's it. I wouldn't even really have a way to know what role you had in the game unless you where the GM.
If you look at the XML source of your feed, you would find entries like this for each game (from my feed):
<entry>

<category scheme="http://m.rpol.net" term="Games You Own" />
<summary>There are no new messages.</summary>
</entry>
The category tag would show if you GM or play/persue. By even with that, if I wanted to see if you GM a game, I could just do a search from the main RPoL page.
This is why I can't send notifications for rMail. It's not listed on the feed. You currently can't check its status without logging in. :(
