US software firm Retina-X Studios has released a more vigilant version of its Mobile Spy program that captures every email and picture from BlackBerry smartphones, prompting Australian privacy advocates to call for order.

"We invite you to open your eyes to the real actions of what your child or employee does on your BlackBerry device," Retina-X chief executive James Johns said in a release.

A spy software makers wants to make sure employers and parents are not in the dark when it comes to phone secrets.

"What if they are being dishonest or worse? The advantages of knowing the answers are far better than not knowing at all."

The previous version of Mobile Spy software kept track of text messaging and telephone calls, providing online access to data by employers, parents or whoever else is paying for smartphone accounts.
