What about privacy?
When you forward your e-mails to your appnotifications address, your e-mails are automatically deleted within few seconds, as soon as your notification was sent. You can delete all notifications shaking your devices, and nothing will be stored on our server anymore. Password are never stored cleartext, neither in the logs neither in the database. They are encrypted using SHA1.
If you have more concerns about this you should use gnupg. You can e-mail us if you need more specific informations.
