Summary (Plain English)
We respect your privacy and have designed Running Pace Calculator with privacy in mind. Here's the simple version:
- We don't collect your personal data. No accounts, no sign-ups, no personal information required.
- Calculations happen entirely in your browser. Your pace times, distances, and running data never leave your device.
- Nothing is stored on our servers. When you close the browser tab, your calculation data is gone. We don't save it anywhere.
The rest of this policy provides more detail for those who want it.
Information We Don't Collect
Running Pace Calculator is designed to work without collecting personal information. Specifically, we do not collect or store:
- Account information: No accounts are required. You don't need to provide a username, password, email address, or any other identifying information to use the calculator.
- Your calculations: The pace times, distances, finish times, and split tables you calculate are processed entirely in your web browser using JavaScript. This data is never transmitted to our servers.
- Health or fitness data: We don't track your running history, training data, or any health-related information.
- Financial information: The calculator is free. We don't accept payments and therefore don't collect any financial data.
- Location data: We don't request or track your geographic location.
Information That May Be Collected
While we don't collect personal data, some information may be collected through standard web technologies:
Analytics
We may use basic analytics services to understand how our website is used. This typically includes anonymous, aggregated data such as:
- Number of page views
- General geographic region (country level)
- Device type (desktop, mobile, tablet)
- Browser type
- Referring website (how you found us)
This data is collected in aggregate and cannot be used to identify individual users. It helps us understand which features are popular and how to improve the site.
Server Logs
Like most websites, our hosting provider may automatically collect standard server log information. This typically includes IP addresses, browser type, and pages visited. This data is used for security purposes and is not used to identify or track individual users.
Contact Emails
If you choose to contact us by email, we receive the information you include in your message (your email address, name, and message content). This data is used solely to respond to your inquiry and is not shared with any third parties. We do not add you to any mailing lists or use your email for marketing purposes.
Third-Party Services
Running Pace Calculator uses the following third-party services:
Vercel (Hosting)
Our website is hosted on Vercel. Vercel may collect standard server logs as described above. You can review Vercel's privacy policy on their website.
We do not currently use advertising networks, and we do not sell or share data with data brokers or marketing companies.
Cookies
Cookies are small text files stored on your device by websites you visit.
Running Pace Calculator uses minimal cookies. We may use:
- Essential cookies: Required for basic website functionality, if any.
- Analytics cookies: If we use analytics services, they may set cookies to track anonymous usage patterns.
We do not use cookies for advertising, tracking across other websites, or building user profiles.
You can control cookies through your browser settings. Disabling cookies should not affect the core functionality of the calculator, as all calculations happen in JavaScript without requiring cookies.
Your Rights
Because we don't collect personal data through the calculator itself, there is typically no personal data to access, correct, or delete.
However, if you have contacted us by email and wish to have your correspondence deleted, you may request this by emailing us at info@runningpacecalculator.org. Please include sufficient information to identify your original message, and we will delete it from our records.
Children's Privacy
Running Pace Calculator is a general-audience website and is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. Since the calculator doesn't require any personal information to use, children can use the calculator without providing any data.
If you believe a child under 13 has sent us personal information via email, please contact us and we will delete it promptly.
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. When we make changes, we will update the "Last Updated" date at the bottom of this page.
We encourage you to review this page periodically to stay informed about how we protect your privacy. Your continued use of the website after any changes constitutes acceptance of the updated policy.
