Privacy
This website runs no third-party analytics or advertising trackers and sets no tracking cookies. The site is served by Cloudflare, which processes technical request data (such as IP address) to deliver and protect it. Fonts are loaded from Google Fonts, which receives your IP address when a page loads.
Buy-link counting
When you click a link to buy a series, the site counts the click anonymously: it records only which series, which link (Gumroad checkout or Gumroad product page) and the date. It does not store your IP address, a cookie, a device identifier or anything else that could identify you. These totals are clicks — not buyers, not sales and not unique people. Actual sales are known only from Gumroad’s own reports.
Buying a series
Complete series are sold and delivered by Gumroad on Gumroad’s own checkout, not on this site. Gumroad collects your payment and contact details, sends your receipt and download link, handles sales tax and refunds, and processes your data under its own privacy policy. We receive the order details needed to support you, such as your name, email address and what you bought. Buy links tell Gumroad which page of this site you came from, so our sales reports can show which series page led to a sale.
Registering interest in a series
If you register interest in a series that is not available yet, we store your email address, the series you chose and whether you also asked to be emailed when it is published. We send one confirmation email through our email provider; nothing counts until you confirm. Confirmed interest is used only to decide which series are written and released first and — only if you ticked that box — to email you once when that series is published. We never send newsletters, sell or share your address. Confirming sets one functional cookie for up to 7 days so you can manage your choices. You can withdraw interest, unfollow or delete your record at any time from your interest settings or the link in our emails. Unconfirmed requests are deleted automatically.
If you email us, we use your message only to reply. For access, correction or deletion requests, contact hello@vellumwise.com.
