We currently maintain a few affiliate partnerships, including Amazon, ProtonMail, SLNT, and others. If you purchase items from these services through links in this website, the companies know that you were directed by us. We cannot see any personal information and we do not know your name or address. We receive absolutely no information about you or your order.
We currently sell our digital guides through Sendowl. While we collect no analytic data from our internal pages, Sendowl collects some basic data about you and your order, including a browser cookie if you place an item into their "cart". We see the name and email you provide to them during checkout, but we do not see or store your full credit card information. Sendowl only shares that data with our credit card processor Stripe.
We have never provided any internal customer, member, or visitor information to any entity. We will never share or sell any information to any third-party company. We have not received any court orders for any data. In 2021, our office received an email request for member search logs from a government agency. No details could be provided as we maintain no visitor usage logs, aside from temporary mandated page access statistics stored by our web host, which is flushed every 24 hours. As this was not an official U.S. court order, we did not respond.

Individual orders available on each book page. PDFs will be immediately available for download after purchase, and an email will also include the download link. You must provide an email address where we can reach you to deliver any updates. This can be a masked, forwarding, or private email provider, but please do not use temporary addresses which you will not be able to control in the future. All PDFs will include a visible and hidden watermark with your order number, but will not include your name, email, or any other personally identifying text. All orders are delivered via SendOwl, and purchasing details are submitted through our own Stripe account. We do not store your credit card information. Due to the nature of instant delivery of digital products, all sales are final.
