Privacy Policy
We collect as little as we can and nothing we don't use.
Hosting
The site is hosted on Cloudflare, which processes standard request data (IP address, browser) to serve pages and protect against abuse.
Analytics
We use PostHog to understand which pages and products people visit: pages viewed, the site you came from, campaign tags, device type and approximate country. PostHog may record anonymized session replays to show where a page is confusing; form inputs are masked and payment details never pass through this site. We honor the Do Not Track setting for PostHog.
If you join a list, we store your email address to send what you asked for. Marketing emails always include an unsubscribe link. Receipts and download emails are transactional and come from the checkout provider.
Feedback
If you send feedback, we receive your message and, only if you give it, your email address, to reply.
Purchases
Checkout is handled by our payment providers (Gumroad and, for some products, Stripe). They process your payment details under their own privacy policies; we receive order details such as the product and price, not your card number.
Your choices
You can block analytics with your browser's tracking protection or Do Not Track, unsubscribe from any email, and ask us to delete your email address.
