If you think we should word the privacy policy differently, please do submit some feedback on kagifeedback.org with the specifics - we have changed it in the past through exactly this process. It has been written by engineers, mostly for engineers at the beginning. I'm sure we can improve the wording to make it more binding, we're not trying to squirrel away from it. If you have enough legal knowledge to harden it, we'd welcome the contribution :)
