Any email is direct to me; I will save a copy, but your addresses are not used for any commercial or bulk sneding and not sold or passed to anyone.

Google Analytics is used to track page views, but this does not track anything which isn't normally available to any site you visit.

If you visit Amazon via a link from my site they will place a cookie on your system so that if you make a purchase they know who refered you.

Similary any of the pay-per-click advertising will note your visit so that I can be paid.
