Can people see who I call on Skype?

No one can see who your Skype contacts are unless they are peering over your shoulder when you check-in or unless your computer has been hijacked. Even if your privacy settings are adjusted, Skype does not give a way to make your contacts public. You may, however, allow others to see how many Skype connections you have. While on a call or an instant messaging chat, you may also share your contacts with other Skype contacts.
