Scriptable and available for anybody. That my contacts in WhatsApp can correlate my activities with my status, this is part of the purpose of WhatsApp, that any stranger having my mobile phone from my business contact can do it, this is another matter.

Edit: Discovered that one can share only with "My Contacts" these information. I am surprised I haven't seen this before or maybe the if you do not share, you cannot see info box misguided me into not restricting to my contacts these informations.
