I don't collect any personally identifiable information if you just visit the site. I do collect aggregate statistical information about site visits so that I can modify the site to make it more interesting and easier to navigate, and to get some sense of how many people are looking at my glass. If you send me an e-mail or give me something with your address on it, I may use that information to send you e-mails or correspondence regarding my work or regarding upcoming events that I am participating in, like holiday open houses. I do not sell the information. If you don't want to be on my mailing list, just let me know by sending an e-mail to firstname.lastname@example.org.
