Privacy Policy

All calculators on RollingSpec run entirely in your browser. The tire and wheel dimensions you enter are never transmitted to a server or stored anywhere — calculations happen locally on your device using JavaScript, and inputs disappear when you leave the page.

Hosting logs

Like any website, our hosting provider may keep standard server logs (such as IP address, browser type, and requested page) for security and operational purposes.

Analytics and advertising

If analytics or advertising (such as Google AdSense) are enabled on this site, those third-party services may use cookies or similar technologies to measure traffic or serve ads. You can control cookie behavior through your browser settings.

We do not sell personal data.
