Your stuff stays yours.
This is a small site run by one parent. Here is everything it knows about you, in plain words.
What we collect
Our sign-up form collects your name, email, and the boxes you tick. We do not add analytics or advertising trackers to this website. Book purchases take place on Gumroad, which processes checkout and provides the downloads under its own privacy policy.
Why
We use sign-up information to email you about the things you ticked. Purchase information is used to deliver your books and help with order support.
Where it is kept
Sign-up submissions are kept in our web host's form inbox. Gumroad manages book orders and makes customer and order information available to us for delivery and support. We do not sell your information.
How to be removed
Reply to any email we send and ask. We will delete you.
What your browser remembers
Your browser saves two small settings on your own device: Stillfire mode on or off, and sound on or off. They never leave your device. Clear your browser data to wipe them.
Who else sees your visit
- Google Fonts sends lettering on the main website. The book shop uses fonts hosted with our site.
- Gumroad handles book payments, receipts, and downloads on its own website. We do not receive your full payment-card details. See Gumroad's privacy policy.
- jsDelivr sends the code that draws the 3D logo.
- If you send a gift, the payment service you pick (CashApp, Venmo or PayPal) handles it on their own site. We never see your card.
Each of these has its own privacy rules.
Kids
This site is for parents and grown-ups. We do not knowingly collect information from children under 13. If you think a child has signed up, tell us and we will delete it.
