Privacy policy

Effective date: September 1, 2026

Numerandi is operated by Numerandi / Chris Mitchell. This policy explains how this website handles information when you use its calculators and pages.

Calculations and personal data

Numerandi tools run entirely in your browser. Values you enter into a calculator are processed on your device and are not sent to Numerandi. The site has no accounts, database, server-side calculator functions, or contact forms, and Numerandi does not currently collect personal data.

As with most websites, the hosting provider may process basic technical request data needed to deliver and secure the site, such as an IP address, browser information, requested page, and request time. Numerandi does not currently use analytics or tracking scripts.

Cookies and local storage

Numerandi does not currently set advertising or analytics cookies and does not use browser storage to track you across sites. A future tool may save a preference on your device; if so, that behavior will be explained where it is used.

Advertising

Numerandi may add advertising in the future. Advertising providers, including Google AdSense, may use cookies or similar technologies to serve, measure, or personalize ads. Before ads go live, this policy will be updated and any consent controls required by applicable law will be added. You can learn about Google's use of information on sites that use its services inGoogle's partner-sites policy.

External links and changes

Numerandi may link to other websites. Their privacy practices are governed by their own policies. This policy may change as the site adds features or legal requirements change. The effective date above will be revised when material updates are published.
