Privacy Policy
Short version: we collect very little, we don't run ads, and we never sell your information.
What we collect
Purchase information. Checkout is handled by Gumroad. We receive your email address and order details so we can deliver files and send the update notices you purchased. We never see or store your full payment card details — Gumroad and its payment processors handle those under their own privacy policies.
Correspondence. If you email us, we keep the correspondence so we can help you.
Site analytics. We may use privacy-respecting, aggregate analytics to understand which pages are useful. We do not use advertising trackers or sell data to ad networks.
How we use it
- Delivering purchased files and the update notices included with your purchase or membership
- Responding to support requests
- Operating, securing, and improving the site
We send product-update emails to buyers because update delivery is part of what you purchased. Any other marketing email will include a working unsubscribe link.
What we don't do
We do not sell or rent your personal information, and we do not share it with third parties except the service providers needed to run the business (payment processing, email delivery, hosting), each bound to use it only for those services, or where required by law.
Your choices and rights
You can request a copy of the personal information we hold about you, ask us to correct it, or ask us to delete it (except records we must keep, such as purchase records) by contacting us — see Contact. California residents may exercise applicable rights under the CCPA/CPRA the same way; we do not "sell" or "share" personal information as those laws define the terms.
Data retention and security
We keep purchase records for as long as needed for accounting, update delivery, and legal obligations, and we use reasonable safeguards appropriate to a small digital-products business. No internet transmission is perfectly secure.
Changes
If we change this policy, we'll post the revised version here with a new effective date.
