Can my icloud account tell other people about my location and other informations?

I just went from android to iphone 6s there are apps like FIND MY IPHONE AND FIND FRIENDS ETC i just want to know if people can know my location informations? Because i don't want that. If they can so can you please tell me how to turn it off or some way?

It can tell them whatever you put up there - most cloud sites have been hacked at one time or another.

You can turn those off. Though you should keep Find My iPhone on for obvious reasons. Just check the settings for those apps.

As long as you are the only one that has your icloud account and password and are not sharing it with someone then you are fine. Put find my iphone on there though, you will be the only one that can access it but it has alot of great features especially if your phone is stolen or lost.
