Privacy & external links

Updated November 1, 2026.

Reading and downloading

The website does not ask you to create an account, submit an email address or fill in a form to read its guides or download the sample chapter. The website uses self-hosted Umami analytics on analytics.makedigitalproducts.com to understand traffic sources, page views and interactions. It does not use advertising pixels or analytics cookies, and does not store analytics identifiers in your browser. The tracker respects your browser’s Do Not Track setting.

Hosting

The hosting provider may process technical information, such as IP addresses and request logs, to serve and protect the website.

Campaign links

If you arrive through a campaign link, the site carries the standard UTM source, medium, campaign, content and term parameters into page links and the Gumroad purchase link. This helps preserve the campaign context. The site does not store these parameters in cookies or browser storage, and records them in the analytics hosted on our own server. Use campaign tags for campaign names, never for personal information.

Gumroad and other external links

Links to the author's Gumroad shop take you to a separate service. Any account, payment or purchase information is handled there under that service's own policies. This website does not receive payment details.

What analytics records

The analytics records page paths and titles, referring websites, standard UTM campaign tags, browser and device information, approximate location, clicks to the book checkout and clicks on the free sample. An article engagement event means at least 30 seconds in a visible tab and scrolling through at least half the article; it does not prove that the article was read.

IP addresses and browser information are processed by our server to estimate location and create a temporary hashed visitor identifier. Raw IP addresses are not stored in the analytics database. Hosting and security logs may still contain technical request information. We do not send email addresses, form contents, arbitrary URL query parameters or advertising click IDs to this analytics service. We do not enable session recordings, heatmaps or personal user identification.

Checkout clicks are measured on this site. Completed payments and customer details remain with Gumroad; a click does not confirm a sale.
