Your user profile has information about the Circles / Avatars you have. Avatars display the information you have entered at the time of Avatar creation (e.g. name, location, photo, stories). Your phone number is hidden from other users if you have created a People (Hobby / Profession) Avatar, phone number is visible only for Business, Event or NGO Avatar. Similarly, the full text address is visible only for Businesses, Events and NGOs and not for People Avatars.
