Short, because there’s little to tell.

What we collect: your email address, when you subscribe. That’s the whole list.

Who processes it: our email provider (Buttondown), which stores the list, sends the emails, and handles confirmations. We use double opt-in — you get nothing until you confirm.

What we don’t do: no tracking cookies on this site, no selling or sharing the list, no enrichment, no retargeting. We use privacy-friendly, cookie-free analytics to count page views.

How to make it stop: every email has an unsubscribe link, handled instantly by the provider. For anything else — including asking what we hold about you (it’s the email address) — write to xin.ryan.xu@gmail.com.
