Privacy Policy
Last updated: January 1, 2025
Overview
Endurance Toolbox ("we", "our", or "us") respects your privacy and is committed to protecting your personal data. This privacy policy explains how we collect, use, and safeguard your information when you use our website and calculator tools.
Information We Collect
Data You Provide
Our calculators process data you enter (such as pace, distance, weight, and heart rate) entirely in your browser and is not stored permanently unless you explicitly save it to local storage. If you create a race-checklist share link, the selected checklist data is encoded in the URL fragment and is visible to anyone you give that link to; analytics and ads are disabled on those shared-link views.
Automatically Collected Data
We may collect anonymous usage data through analytics services, including:
- Pages visited and time spent
- Device type and browser
- Approximate geographic location (country/region)
- Referral source
How We Use Your Data
We use collected data solely to:
- Improve our calculators and user experience
- Understand which tools are most useful
- Fix bugs and technical issues
- Display relevant advertisements (if applicable)
Cookies & Local Storage
We use cookies and local storage to:
- Remember your preferences (dark mode, unit system)
- Provide analytics functionality
- Enable advertisement personalization (if ads are shown)
You can clear this data at any time through your browser settings.
Third-Party Services
We may use third-party services that collect data according to their own privacy policies:
- Google Analytics (analytics)
- Google AdSense (advertising)
- Cloudflare (hosting and security)
Your Rights
Depending on your location, you may have the right to:
- Access your personal data
- Request deletion of your data
- Opt-out of analytics tracking
- Disable personalized advertising
Data Security
We implement appropriate security measures to protect your data. Our site uses HTTPS encryption for all connections. Since calculator data stays in your browser, there is minimal risk of data exposure.
Children's Privacy
Our services are not directed at children under 13. We do not knowingly collect personal information from children.
Changes to This Policy
We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
