Privacy, simply.

Your calculator inputs stay in your browser. We do not collect the prices, costs or targets you enter.

If you allow measurement, this site records a random visit identifier, the campaign link used, the date and which steps you use: opening the page, calculating, opening the checklist, clicking the email signup link and clicking the product link. These are approximate sessions, not a count of individual people. Blocking measurement means we cannot count your visit.

The random identifier is kept in session storage. Your measurement preference stays in local storage until you clear it or change it using “Measurement preferences” on the home page. Measurement records are retained for up to 180 days.

Cloudflare hosts this site and processes ordinary connection information to serve and protect it. We do not save raw IP addresses in our application database.

Email signup is optional. The form explains the three emails you will receive. EmailOctopus stores and sends email to subscribers; each marketing email includes an unsubscribe option. No marketing list is created from calculator use alone.

Gumroad handles checkout, payment and delivery. Their privacy terms apply on their site. Our private experiment report may synchronise purchase amounts, test/refund status and hashed customer identifiers to avoid counting repeat buyers as new customers. It does not store customer email addresses.
