Small Rig Math has no accounts and no sign-up. The numbers you type into the calculators are saved only in your own browser (local storage) on your device so they are there next time. They are not sent to us.
If you join the Pro waitlist, we store your email address, the features you picked, your truck type, language, the page you signed up on, your country (from Cloudflare) and the date. We use it only to tell you when Pro launches and about the early price. We never sell or share it. To remove your email, check "Remove my email from the list" in the waitlist form and submit your email again.
When you open the waitlist form we also count the click (page address and time only, no personal data), to see how many people are interested.
The site is hosted on Cloudflare. Like any website host, Cloudflare may process basic technical request data (such as IP address and browser type) to deliver and protect the site.
We do not use advertising or tracking cookies at this time. If that changes, this page will be updated first.
To remove your saved numbers, clear this site's data in your browser settings.
All results are estimates for planning only and are not tax, legal, or financial advice.
