Privacy Policy

Last updated: November 2, 2026.

Our free calculators run entirely in your browser; inputs are never sent to us. We do not use advertising cookies. Payments are processed by Stripe, which receives your payment details under its own privacy policy; we receive your name, email and order details to deliver your purchase. We use your email for order delivery and support. At checkout, the “Send me weekly Excel ideas” option is pre-set to “Yes”. Only buyers who leave it on “Yes” are added to our weekly newsletter (hosted by beehiiv); if you switch it to “No thanks”, you are never added to the newsletter. You can unsubscribe anytime via the link in every email. Buyers in the EU, EEA, UK and Switzerland are not subscribed unless they sign up separately. You can also sign up on this site. To access or delete your data, reply to your Stripe receipt email.
