Privacy

Short version: this site collects nothing.

The calculator runs entirely in your browser. Your inputs are never transmitted, stored or logged by us.
There are no user accounts on this site.
We do not sell, rent or share personal data — we never receive any.
If you buy the Pro Kit, checkout is processed by our payment partner (Payhip or Gumroad) under their own privacy policy. They send us only the minimum sale information needed for records (product, amount, country, and the email you use for delivery).
If optional, cookie-free aggregate analytics are enabled by our host, they report page counts only — no individual tracking, no advertising cookies.

Questions: reply to any purchase receipt, or use the contact address shown on the checkout page.
