Privacy Policy

Last updated: June 30, 2026

Overview

Ryutility ("we", "us", "the site") provides free web-based tools at ryutility.com. This policy explains what information is collected when you use the site, how it's used, and the choices available to you.

Information we collect

The tools on this site run entirely in your browser. Calculator inputs (such as race times or personal metrics you type in) are processed locally on your device and are never sent to our servers or stored by us.

If you accept the cookie banner, we use Google Analytics (GA4) to understand aggregate site usage — pages visited, approximate location (derived from IP address), device and browser type, and referral source. This data is not linked to your name or any other directly identifying information we collect, because we don't collect any.

Cookies

We use a small number of cookies and browser local storage:

• Consent preference — stored in your browser's local storage to remember whether you accepted or declined analytics cookies.
• Google Analytics cookies — set only after you accept the cookie banner, used to measure site usage as described above.
• Advertising cookies — once this site displays ads via Google AdSense, Google and its partners may use cookies to serve ads based on your visits to this and other sites. See "Advertising" below.

Advertising

This site may display ads served by Google AdSense. Google uses cookies to serve ads based on a user's prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings, or by visiting aboutads.info (US) or youronlinechoices.eu (EU).

Your rights (GDPR / CCPA)

If you are located in the European Economic Area, you have the right to access, correct, or request deletion of any personal data we hold about you, and the right to withdraw analytics consent at any time by clearing your browser's local storage for this site.

If you are a California resident, you have the right to know what personal information is collected and to opt out of its "sale" or "sharing" (as those terms are defined by the CCPA/CPRA). We do not sell personal information. You can limit analytics and ad personalization using the tools linked above.

Data retention

We do not operate a server-side database of visitor information. Any data collected via Google Analytics is retained and governed according to Google's own data retention settings and policies.

Children's privacy

This site is not directed at children under 13, and we do not knowingly collect information from children.

Changes to this policy

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