I collect two pieces of information:
On all visitors: anonymized information of who visited my website. If you're curious what I track—see for yourself.
On some visitors: your email address. If you signup for my mailing list (you should, it's awesome), then I have your email address. You can unsubscribe at any time; simply click the 'unsubscribe' link in the bottom of any email you receive from me.
And, as a matter of course, I do not log visitor's IP addresses.
And nor do I set any cookies.
So browse all you want; I have no idea who you are unless you tell me.
