When you make a purchase, we receive your name and email address from our payment processor so we can deliver your digital products. If you contact us by email, we receive whatever information you include in your message.
Payments are processed by Lemon Squeezy and Gumroad. They handle all credit card information directly — we never see or store your card details.
We use your information only to deliver your purchases, provide customer support, and operate the membership license system. We do not sell, rent, or share your personal information with third parties for marketing purposes.
Our site is hosted on GitHub Pages and does not set tracking cookies. Our payment processors may use cookies during checkout as described in their own privacy policies.
We keep purchase records only as long as needed to provide support and comply with tax and accounting obligations.
