Your app may break after April 30, 2015

I have a Facebook App only for development and tests. Its status is "not public" in the "Status & Review" page. This means that the app is offline and only accounts registered in the app can access it.

The app requests the following permissions to the registered users: email, public_profile, user_friends, user_photos and user_videos. For public apps, the last two permissions (user_photos and user_videos) need to be approved by Facebook. This process is part of the Login Review described here. Whenever an user logs in the public app that didn't pass by "Login Review" process, the login page presents the message "Your app may break after April 30, 2015. Some of the permissions below have not been approved for user by Facebook. Submit for review now or learn more."

However, I am a little bit worried because my app is not public and even so it is showing the same message. Is the "Login Review" process necessary for non public apps? Non public apps can break after this date too?

Thanks
