Policy
Privacy
Short version: this site does not track you, and nothing you type in the online calculators leaves your browser.
This website
- No analytics, no advertising pixels, no cookies set by PrimeCost Lab.
- The online calculators run entirely in your browser. The numbers you type are not sent or stored anywhere.
- The site is hosted on GitHub Pages and uses Google Fonts. Like any web server, those services receive your IP address when your browser loads the page; their own privacy policies apply.
Purchases and free downloads
Downloads and payments go through Gumroad, which asks for your email to deliver the file and processes the payment. PrimeCost Lab never sees your card details. Gumroad's privacy policy applies to that step.
If you write to outilfinance@gmail.com, your message is used only to answer you. It is not sold, shared or added to a mailing list.
Custom model questionnaires
Numbers you send for a custom model are used only to build your model and are not shared.
