Cryptocat on a Windows OS or Chrome browser

Comment by pyrih
about Cryptocat and Windows 8, Off-the-Record Messaging, Google Chrome Sep 2013

Can anyone confirm if using Cyptocat on a Windows system could lead to losing one's private keys to Microsoft (and therefore, the NSA)?

Same thing for the Chrome browser: could Google (and therefore, the NSA) get a hold of your Cryptocat private keys if you are using Cryptocat as a Chrome extension?
