PrivacyGrade: Grading the Privacy of Smartphone Apps

It might be "A" for the expected permissions, but if there's extra permissions which haven't been investigated, these should be marked down until explained. This would encourage app owners to work with whoever maintains the database to get accurate ratings. If Whatsapp is an A today, there's no incentive for the developers to justify / assist with anything unexplained permissions remaining.
In it's current state, if it's awarding A scores while significant permissions are unexplained, it doesn't help the end user.
I suppose the above is more of a "security" concern than a "privacy" concern, but I think they are ultimately one and the same.
Anyway, it's an impressive website, good to see new work being done in this area. Access to smartphone data is a wild west at the moment.
