Privacy policy.

We collect the minimum data needed to run the site, and send the email digests you opt into. We don't sell or share data with third parties beyond the operational vendors listed below.

What we collect

• Email address when you opt into a list (calculator results, weekly digest).
• Anonymous usage analytics via GA4 (page views, calculator inputs, conversion events).
• Brand enquiries sent through the race partners form: your name, email, brand, website, the race window and your message, plus the page you sent it from.
• Coaching applications sent through the coached plans form: your name, email, fitness level, how often you train, your best HYROX time and target race if you give them, your goals and your confirmation of the program terms, plus the page you sent it from.

How we use it

• Send the email content you opted into (and nothing else).
• Improve the calculators + content based on aggregated usage patterns.
• Answer a brand enquiry. It goes to our partnerships team and into our contact records, and we use it only to reply and manage that partnership.
• Answer a coaching application and, if you go ahead, build and adjust your plan. It goes to Thomas Prommer and into our contact records.

Vendors

• Sendy: email delivery (self-hosted)
• Google Analytics 4: anonymous usage analytics
• Cloudflare: CDN + DNS
• DeepL: translation pipeline (your content is not used for training)

Cookies

We use minimal cookies: session cookie for calculator state, GA4 analytics cookie (anonymized). EU visitors see a consent banner before any non-essential cookies load. You can withdraw consent at any time via the cookie banner footer link.

For the avoidance of doubt: we don't sell your data, ever.
