Cover selections and, if offered, a short written note about them. Purchase intent and the four price figures, when given. An email address, only if one is submitted.

A visit is also recorded: the page opened, the referring address and any campaign tags in the link. A random session identifier is stored in this browser so a single visit is not counted twice.

No names, no addresses, no payment details. No advertising or third-party tracking scripts. No cookies beyond the local session identifier kept in this browser.

To understand which covers are noticed and what the object is worth to the people who notice it. Votes and price answers are read in aggregate. Emails are used for one note when the first edition is ready.

In a managed database hosted by our infrastructure provider on servers within the European Union. Access is limited to the person running this project.

Votes and price answers are kept for as long as the research is useful, then deleted. Email addresses are kept until the launch note is sent, or until removal is requested — whichever comes first.

Ask, and any record connected to an email address will be shown or deleted. Write to hello@umbraliamatter.com.

Nothing is sold, rented or passed to marketing lists. Data is handled only by the hosting and email providers needed to run this page.
