Locking the Eve app?

So I used to have an iPhone but in an unfortunate turn of events I lost it, so I had to get a more inexpensive Samsung. So now I have this Android processing system and I noticed that I have no option to lock the eve app with a pin code or password like I did with the IOS app. Am I missing something or is this feature not available on Android yet? If it is not available I really hope that you guys will make it available, maybe add in the next update? I just don't feel comfortable leaving the app unlocked. I have a lot of family with a lot of little kids, a lot of smart kids, so even if my phone is locked... I would like eve to be locked.
