Privacy Policy

Running Calcs ("we", "us") operates www.runningcalcs.com. This policy explains what information is collected when you use the site and how it is used.

Information we collect

Running Calcs is a static website. Calculator inputs are processed in your browser and are not sent to our servers. If you use shareable links, values may appear in the page URL on your device and in any service you share that link with.

We use Vercel Analytics and Google Analytics to understand aggregate site usage and performance. These services may collect information such as pages visited, browser type, device type, and general location derived from IP address. We do not use these tools to identify individual users.

Cookies and local storage

Vercel Analytics and Google Analytics may use cookies or similar technologies to measure traffic. Running Calcs does not set cookies for authentication, advertising, or storing calculator data.

How we use information

Aggregate analytics help us understand which calculators are useful, monitor site performance, and improve the service. We do not sell your personal information.

Third-party services

Analytics data is processed by Vercel and Google. Their handling of data is governed by Vercel's Privacy Policy and Google's Privacy Policy. The site is hosted on Vercel's infrastructure.

Your choices

You can use browser privacy settings, extensions, or network-level blocking to limit analytics collection. Because calculator data stays in your browser, clearing your browsing history or avoiding shared links removes those values from your session.

Children's privacy

Running Calcs is intended for a general audience and does not knowingly collect personal information from children under 18.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated revision date.
