Keeping it short and sweet:
- This website collects zero data about visitors (unless you choose to provide information, such as by using one of the indicated contact email addresses).
- The hosting company gathers statistics about traffic to and from its servers (including the server hosting this website, among many) but not about individual visitors.
- If a link you click on this website takes you to another website, its privacy policy takes over.
- Sitemeter collects statistics on accesses to this website (again, as one among many), in this instance for the use of the webmaster. The Sitemeter privacy policy is here. “Customer” in that policy refers to Edward M. Lerner (to whom this website is registered), not to you, the reader.
- And a final disclosure:
This website is a participant in the Amazon Services LLC Associates Program, an affiliate 
advertising program designed to provide a means for sites to earn advertising fees and linking to amazon.com.
and
Amazon and the Amazon logo are trademarks of Amazon.com, Inc. or its affiliates.
#5 means, in English, that if a link takes you to Amazon.com and you buy the associated product within what Amazon deems the appropriate time frame, Ed may be paid a small commission. He won’t get rich thereby, and you won’t have paid any more than if you’d gotten to that Amazon page by another route.
