Are you using Skype? If so, perhaps you should switch to something that is more secure.
Brian Fagioli shares a report from BetaNews:
“So, here’s the deal, folks. In order for this magical “in-context” technology to work, Cortana is constantly reading your private conversations. If you use Skype on mobile to discuss private matters with your friends or family, Cortana is constantly analyzing what you type. Talking about secret business plans with a colleague? Yup, Microsoft’s assistant is reading those too. Don’t misunderstand — I am not saying Microsoft has malicious intent by adding Cortana to Skype; the company could have good intentions. With that said, there is the potential for abuse. Microsoft could use Cortana’s analysis to spy on you for things like advertising or worse, and that stinks. Is it really worth the risk to have smart replies and suggested calendar entries? I don’t know about you, but I’d rather not have my Skype conversations read by Microsoft.”
