Generally, I do not collect or store private information.
When people sign up for my newsletter, their email addresses are automatically added to a list kept by MailChimp. I never look at individual addresses and no other personal information is collected or stored. Nor will I ever share or sell those email addresses. And anyone who wishes to be removed from my mailing list can unsubscribe at any time. (And here’s the link to MailChip’s policy: https://mailchimp.com/legal/privacy)
