Yes and no on that. Sure it is possible. Anything with an internet connection is accessible to the wrong people, theoretically at least. Realistically though, you should be fine. It should take quite a bit of effort on the voyeur's end to achieve this, probably requiring them to have physical contact with your device. There are added security measures you can do to your device like password lockscreen and/or some sort of security app (like https://play.google.com/store/apps/d...id=com.lookout <-- that seems to be popular) if you want extra peace of mind.
