Hmm. I don't think chat conversations are secure (Encrypted) unless they changed it recently. Everything is is via an unencrypted transaction. So your message may be intercepted by Uncle Sam or Gyane if they wanted to. In that sense even Cell phones are not secure. Even though you are not involved in active conversations, your cellphone is always talking to the base station and information is transmitted back and forth. So if uncle sam wanted, they could listen to what you were talking about from the cellphone's mouthpiece without you knowing that.
