Secure Contact Delete

I have published one more application on the Google Play Store, named "Secure Contact Delete".

The application deletes ALL contacts on the phone, after overwriting all information fields with random text. This ensures that once deleted, the contact information cannot be retrieved.

To stop inadvertent deletion, the application asks for a PIN at start up, which is stored in an application database. Whenever the 'delete' option is chosen, the application asks for a PIN. Only if the provided PIN matches the stored PIN, the contacts are deleted.
