What is collected
If you only read this site, nothing personal is collected beyond ordinary anonymous traffic information such as pages visited and approximate location.
If you order the Manual, the payment is handled by Stripe. They receive the details you enter at checkout, such as your name, email address and card information. The card details never reach this site.
What it’s used for
Your email address is used to send your copy of the Manual, your receipt, and any later revision of the book you already paid for. Nothing else.
Your information is never sold, rented or shared with advertisers.
Purchase emails are transactional. If a newsletter is ever offered, it is opt-in only and every message has a one-click unsubscribe link.
Your choices
You can ask to see or delete the information held about your order at any time by replying to your receipt.
