The short version: calculaterun.com does not collect personal information to sell or share with third parties. This page explains in plain terms what data is collected, why, and how it is used.
1. Who We Are
calculaterun.com is an independent running tools and resources website. References to "we," "us," or "our" in this policy refer to the operator of calculaterun.com. For questions, see the Contact section below.
2. Information We Collect
We collect minimal information, and only what is necessary to operate the site:
- Usage data. If analytics are enabled, we use Google Analytics to understand how visitors use the site — which pages are visited, how long visitors stay, and what devices and browsers are used. This data is aggregated and anonymized. We do not use it to identify individual visitors.
- Cookies. Advertising and analytics services may place cookies on your device. You can control these through the "Cookie settings" link in our footer, through your browser settings, or with a browser extension.
- Calculator inputs. The running calculators on this site run entirely in your browser. Input values such as race times, distances, and paces are never transmitted to our servers or stored anywhere.
3. Consent
When you first visit, a consent banner lets you choose whether to allow advertising and analytics cookies. We use Google Consent Mode v2: until you choose, ad and analytics storage default to denied. You can change your choice at any time via the "Cookie settings" link in the site footer.
4. Google AdSense
This site uses Google AdSense to display advertisements. Google may use cookies to serve ads based on your prior visits to this site and other sites. You can opt out of personalized advertising by visiting Google's Ads Settings or aboutads.info.
For more information on how Google uses data when you use partner sites, visit google.com/policies/privacy/partners.
5. Amazon Associates
calculaterun.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program. When you click an Amazon link on this site and make a purchase, we may earn a small commission at no additional cost to you. Amazon has its own privacy policy governing data collected through their platform.
6. Third-Party Links
This site may contain links to external websites. We are not responsible for the privacy practices of those sites and encourage you to review their policies independently.
7. Children's Privacy
calculaterun.com is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal information through this site, please contact us and we will remove it promptly.
8. Data Retention
We do not store personal data on our servers. Data held by third-party services (such as Google) is retained according to those services' standard data retention policies.
9. Your Rights
Depending on your location, you may have rights regarding your personal data under laws such as the GDPR (European Union) or CCPA (California). Since we collect no personal data directly, most of these rights apply to data held by third-party services (Google Analytics, Google AdSense, Amazon). You can exercise those rights directly with those providers, and you can withdraw cookie consent at any time via the "Cookie settings" link in our footer.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected by an updated date at the top of this page. Continued use of the site following any changes constitutes acceptance of the revised policy.
