Privacy policy

Last updated October 29, 2026

Calculators. Everything you type into a calculator stays in your browser. We don't send it to a server or store it.

Newsletter. If you subscribe, your email address is stored by our newsletter provider (beehiiv) so we can send you emails. You can unsubscribe at any time using the link in every email.

Analytics. We may use privacy-friendly, cookie-free analytics to count page visits. We do not sell personal information.

Links. Some links go to other sites, such as our shop. Their privacy policies apply there.

Paid links. Some links on this site may be paid links. When you click one, you leave our site. The company you visit, or the network that tracks the link, may place or read cookies in your browser to record that you came from us, so it can pay us a commission. That happens on their site and is covered by their privacy policy. Any network we work with will be listed on our disclosure page, with a link to its privacy policy. If we ever show a partner's product box on a page, that partner may serve the content, collect information directly from you, and place or read cookies. You can block or delete cookies in your browser settings, and you can opt out of interest-based ads at optout.aboutads.info and optout.networkadvertising.org.

Custom order requests. If you send a custom order request, the details you enter (your name, email, phone number if you add one, delivery city and state, the order details and any files you upload) are emailed to our shop inbox so we can reply with a quote. We keep that email as our record and don't add it to any other list. If you go ahead with the order, we share your design and delivery details with our print partner so it can make and ship your items.

Planner app. If you use the Steady Sums Planner, we store your email address and the numbers you enter in your account so they sync across your devices. Other people can't see your account, and we never sell your data. Payments are handled by Stripe, so we never see your card number. The Planner has its own privacy policy with more detail.

Do Not Track. We don't track you across other websites, so there's nothing for a Do Not Track signal to switch off on our side. Affiliate networks may collect information about your activity over time and across sites; their own privacy policies explain how they handle Do Not Track.

Children. This site is meant for adults. We don't knowingly collect personal information from children under 13.

Your choices. Email us at [email protected] to have your newsletter, custom order or Planner account information deleted.

Changes. If we change this policy, we update the date at the top.
