The calculator runs in your browser. We do not send its values to a server, save them in cookies or local storage, or collect an email address through a form on this site.

The formula-check inquiry link opens your email app. Nothing is sent until you send the email. Your email address and message then reach our Gmail inbox so we can respond to your inquiry; this does not subscribe you to a mailing list. Please begin with a description only, without attachments or client details. We confirm permission and handling before reviewing any sample with AI-assisted tools.

The hosting provider may process routine connection information such as IP addresses and request logs to serve and protect the site. Downloads are served by this host. No advertising pixels or third-party analytics have been installed by the seller.

If you follow a Payhip checkout link, Payhip and the connected payment provider process your order under their privacy policies. Review the seller contact details and purchase terms at checkout.
