This website doesn't use analytics cookies, tracking pixels or third-party scripts. The free calculator runs entirely in your browser. Nothing you type into it is sent anywhere. If you switch the site's sound effects on, that choice is remembered in your own browser's local storage.
When you buy, payment is processed by Gumroad (acting as merchant of record), which collects your name, email, payment details and billing country to process the order, handle tax and send your download. We receive your name, email and order details so we can provide support and refunds. We never see your full card details.
The kit works offline. The chase tracker saves only to your own browser's local storage. We can't see it.
Emails: we'll only email you about your order, plus product updates if you opt in. Every email has an unsubscribe link.
Your rights: you can ask us to access, correct or delete your data at any time by emailing unghost50@gmail.com.
