Terms of use

Built Brains sells digital printable books — PDF files you download and print at home or school. Nothing physical is shipped. Each product page shows the ages, the number of pages and what's inside. Every book comes in a Colourful Edition and a Black & White Edition, each in US Letter and A4.

When you buy, you get a personal licence to print the pages:

• Families: print as many copies as the children in your home need, as often as you like.
• Teachers: print for the children in your own class or group.

Please don't share, resell or upload the files anywhere others can download them (including school-wide drives or teacher marketplaces), or sell printed copies. The illustrations and pages remain the property of Built Brains Academy.

Prices are in US dollars and shown on each product page. Taxes, currency conversion or bank fees may apply depending on where you are. Sale prices apply until the end time shown; the price you pay is the one on the checkout page when you complete your purchase.

Right after payment you land on your download page, and we email you the same link — bookmark it, it's your permanent access. If a download doesn't work, email support@builtbrains.com and we'll fix it.

You can send books as a gift: we email the recipient on the date you choose (in the morning, US time) and send you a printable gift certificate. Please make sure the recipient's email is right — we can resend a gift, but we can't recall one that has gone to the wrong address. The recipient gets the same printing licence as a buyer.

• Gift cards can be used on any Built Brains books and never expire.
• Enter the code at checkout under “Add promotion code”. If your order costs less than the card, we email a new code for the balance.
• Gift cards can't be exchanged for cash, used to buy other gift cards, or combined with some other offers.
• Keep your code safe — treat it like cash. If a code is lost or used by someone else, contact us and we'll help where we can.
• Custom photo cards: only upload photos you have the right to use. We may decline photos that are inappropriate.

Every product has a 14-day money-back guarantee, and unused gift cards can be refunded within 14 days. See the money-back guarantee for how it works.

To deliver your order and run the store we use and share some personal data with the services that help us — Stripe for payments, Resend for email, Cloudflare and Vercel for storage and hosting, and Meta to measure our ads (purchase and sign-up events, with your email hashed). By buying or signing up you agree to this use as described in our privacy policy, which also explains your rights and how to object.

Our activities are made for young children with an adult nearby. Some pages use scissors, glue or small craft items — please supervise, and choose activities that suit your child. Ages shown are a guide; every child learns at their own pace.

We work hard to make our books accurate and useful, and we provide them as they are. To the extent the law allows, our total liability for any purchase is limited to the amount you paid for it. Nothing in these terms limits rights you have under consumer law that can't be excluded.

We may update these terms as the store grows; the current version is always on this page, with the date at the top. Purchases are governed by the terms in place when you bought. Questions? Email support@builtbrains.com.
