The basics-
If you give me your email it will be shared with a 3rd party application.  Quite frankly it's safer than me storing it on my macbook which is usually left lying around.  They won't share it with anyone else and neither will I.
I won't ever sell it.  
I hate junk.  I won't send you junk just things I think you will be interested in but you can unsubscribe at anytime.  Just click the unsubscribe button (but I will have a mini cry as I hate to see you go).  

Private Policy- Yawn, but important yawn!
