We collect only the information you voluntarily provide — such as your email address when purchasing a book or subscribing to updates. Payment processing is handled entirely by Gumroad and Stripe; we never see or store your payment details.
To fulfill purchases, send updates (if you opt in), and improve our products. We do not sell, rent, or share your personal information with third parties except as required to process transactions (e.g., Gumroad, Stripe).
This site uses no tracking cookies. Gumroad may set cookies during the purchase flow — their privacy policy applies there.
You can request access to or deletion of your data at any time by emailing the contact address on this site.
We may update this policy. Changes will be posted here with an updated date.
