Your calculation
stays with you.
The free sample calculator runs in your browser. It does not save an order or collect payment details.
Sample inputs
Sample quantity and pricing inputs are not sent to an analytics or payment service.
Book purchases
Kindle purchases and reading take place on Amazon under Amazon’s privacy policy.
Optional analytics
With your permission, Google Analytics measures page visits, demo use, checkout clicks and book links. Verified purchases and refunds may be linked using an anonymous analytics identifier. Recipes, costs, customer names, customer quotes, email addresses and bakery workspace data are never sent. Declining does not affect purchases or access. Use Analytics preferences in the footer to change your choice. We do not load advertising pixels.
Purchase and account access
Lemon Squeezy handles checkout. KERUB stores your purchase email, verified payment status and account access records. Resend delivers transactional access and recovery emails. Essential session cookies keep you signed in. Magic links expire after 10 minutes and work once. Sessions last up to 24 hours, or up to 30 days when you choose Remember me on the confirming device. Signing out revokes that device’s session; it does not cancel your purchase.
Your ingredients, recipes, customer quotes and workspace backups remain in your browser or your own downloaded files. They are not synchronized to our server. No advertising tracker is loaded.
