What we collect
This is a simple book information site. We do not ask you to create an account and we do not sell personal data. Aggregate, non-identifying analytics may be collected to understand which pages are useful.
Newsletters
If you subscribe to The Experimental Marketer or A Experimentalista, your email address is handled by those newsletter platforms under their own privacy policies. You can unsubscribe at any time from any issue.
Outbound links
Preorder and assessment links take you to third-party sites such as retailers and the publisher. Once you leave this site, their privacy practices apply.
