Hosting
Like any website, the hosting provider that delivers these pages may process basic technical data (for example your IP address, browser type and the time of the request) in its server logs, to deliver the page and keep it secure.
Purchases
When you click "Get the guide", you leave this site and go to Gumroad, which processes the payment and delivers the files. Gumroad collects the details needed for the purchase (such as your email address and payment information) under its own privacy policy. As the seller, Pini Sapir receives the order details Gumroad shares with creators, such as your email address, and uses them only to deliver and support your purchase.
