First Sale Fees / Field guide
Privacy
The calculators run in your browser and do not ask for customer or payment-account information.
Calculator inputs
Your product prices, sales counts and fee inputs are used in the page to calculate results. This site does not send those inputs to us, save them in an account or store them in browser storage. Reloading the page normally restores the example values. If you open a saved calculation link, its numeric inputs are loaded from the part of the URL after the # symbol.
Calculation links and printing
Copying a calculation link places the numeric assumptions in the URL fragment, after the # symbol. Anyone you share that link with can see those assumptions. The fragment is not sent in the normal page request. The site does not automatically save a calculation or transmit it to an account. Printing uses your browser's print function.
Site delivery
The hosting provider can process standard request information, such as an IP address and requested page, to deliver and protect the site. This version has no advertising pixel, embedded third-party media or newsletter form.
Web analytics
We use Cloudflare Web Analytics to measure page views, visits and page performance. Its beacon does not use cookies or browser storage. Our first-party measurement records aggregate counts for page views, affiliate-link clicks, calculator use and result-save requests in Cloudflare D1. We store the UTC day, page path, a broad traffic-source category, event type, calculator type and predefined link or offer labels. We do not send calculator input values, URL query strings or fragments, full referrer URLs, names, email addresses, IP addresses or visitor identifiers to this measurement database. This measurement does not use cookies or browser storage and is disabled when your browser signals Do Not Track or Global Privacy Control.
External links
When you follow a provider link, that provider's privacy policy applies. Some outbound links contain our affiliate identifier. The destination service may use referral identifiers or cookies to attribute registrations and purchases. Our disclosure explains the current link status.
Information you should not enter
The calculators only need numeric assumptions. Do not enter a password, bank account, payment card, personal identification document or customer record into a calculator.
