The purpose of 'Numeracy' is to help children learn.  As teachers ourselves, we know the importance of protecting childrens' privacy.

This app collects absolutely no information about users.

On installation,'Numeracy' requests access to your photo library, to enable certificates to be created there to show pupil's achievements.  It doesn't itself access any images that are already in your photo library, even the ones that it has created.

To see saved certificates you can use any of the 'Gallery' or 'Camera Roll' apps that are already available on your device.
