+- **What is stored.** Your email address, the updates you chose (recorded as tags on your subscription), and the records our email provider keeps to confirm and deliver a subscription, such as when you signed up and confirmed.
 - **Who handles it.** The list is run on [Buttondown](https://buttondown.com), which stores the address and sends the email on our behalf. Buttondown's [privacy policy](https://buttondown.com/legal/privacy) governs its processing.
 - **Confirmation.** You are not added to the list until you click the link in a confirmation email, so nobody can sign you up without your knowledge.
