If you want to check how your profile looks like in public, do the following steps (I have tried the steps on both computer and iPad no problems):
* Go to your profile and look on top bar for this icon that looks like a cute little padlock.  It's all the way to the right near a drop-down arrow. Click on it.

* Click on 'See  More Settings'. 
* Look for 'Timeline and Tagging Settings' option and  click on the 'View As'. 

* You will be able to see how your profile looks  like if it is being viewed by an outsider in public. You can also type in a specific person's name and see how your profile looks like if it is being viewed by the person.
How  do I define a profile on FB as secure? When you view a profile, you can  only see the least possible info, status updates on timeline and  pictures shared on your profile.  
For  example, if you view my personal FB profile you can only see my current  profile picture and current cover photo, that too I put the same  pictures as what I put on my FB fan page. Also, you won't be able to see  any status updates postings on my timeline except my life events that I  chose to share in public such as the time when my fan page reached 100K  followers, or when I was born. That's all an outsider who is not in my  FB friend list can view if they are able to search up my profile or  clicked into my profile when I commented or liked a posting on FB.
Go ahead and ensure your Facebook profile is as secure as it can possibly be!

If   you    wish  to   ask me any questions, you   can  find     me at my Facebook page (I'm there almost everyday) or just drop me an email if you wish to maintain some anonymity.
