Privacy policy
Last updated 17 April 2026.
What we collect
This site is a static publication. It does not require an account and does not collect personal information from visitors. We use standard server-side request logs (CloudFront) which record IP address, user agent, and requested path for a short retention window. We do not use those logs to build visitor profiles.
Calculators
The fueling calculators on this site run entirely in your browser. Inputs you enter (body weight, pace, finish time, race distance) are processed locally by JavaScript and are not transmitted to any server. If a calculator offers to “remember my numbers” it uses browser localStorage, which you can clear from your browser settings.
Analytics
We do not run third-party analytics (no Google Analytics, no Facebook pixel, no Mixpanel). We may use aggregate CloudFront metrics for capacity planning. No individual-level tracking.
Cookies
The site sets no tracking cookies. If a future feature needs one (for example, remembering your unit preference), it will be strictly functional and disclosed here.
If you email one of the addresses on the contact page, we use your email only to reply to you. We don't add it to a marketing list.
RSS
The RSS feed at /feed.xml is public and unsigned. We don't know who subscribes.
Changes
If the policy changes materially, the “Last updated” date above will change and a note will appear on the homepage for at least 30 days.
