Using this website
This website introduces Sand Castle Science products, provides building guides, and accepts direct orders. We do not use advertising pixels. With your permission, optional Google Analytics measures visits, product interest, Amazon link clicks, video use, checkout starts, and completed website purchases. It does not measure whether an Amazon link click becomes an Amazon purchase. Analytics is not required to use this website or checkout.
Purchases and external links
For direct orders, Stripe processes your payment and stores the email, billing, and shipping information you provide. We use order information to process your purchase, provide support, and arrange shipping through Ideal Fulfillment. We share the information needed to ship your order with our fulfillment provider. Card details are collected by Stripe and are not stored on our website. When you follow an Amazon link, Amazon’s privacy notice and purchasing terms apply.
Technical information
Our hosting providers may process technical information, such as IP addresses and request information, to deliver and secure the website. Checkout uses a secure, essential cookie to associate your browser with its order. Our website stores hashed session identifiers, quantities, payment status, and security records. Stripe stores payment and address details. We limit access to order records to the services and people needed to process and support orders. Contact us about access, correction, or deletion of your information; some records may need to be retained for accounting or order support.
Optional analytics
Google Analytics is loaded only after you choose Allow analytics. It may use cookies and process technical information such as device, browser, and network information. We send page paths and shopping totals, not checkout form fields, email addresses, shipping addresses, card information, or raw payment-session identifiers. URL query strings are removed from the page addresses we send. Advertising personalization and Google signals are disabled. You can decline analytics or change your choice using Analytics preferences in the footer. We honor supported Global Privacy Control and Do Not Track signals. Google privacy information.
