Terms of Use

Last updated: May 11, 2026

1. Acceptance

By installing or using rox-strat ("the app"), you agree to these Terms of Use. If you do not agree, do not use the app.

2. What the app does

rox-strat builds a personalized pacing plan for HYROX®-format races based on the data you provide (a personal fitness test, station personal records, an aggression level) and, optionally, biometric and activity data you choose to share via Apple Health or Strava. On race day, it delivers segment-by-segment guidance through the iOS app and an Apple Watch companion.

3. Not medical or coaching advice

Predicted finish times, readiness scores, fatigue curves, and pacing targets are mathematical estimates derived from public formulas (Riegel) and on-device ML models. They are not:

• medical advice or a diagnosis
• a substitute for guidance from a qualified coach, doctor, or physiotherapist
• a guarantee of any race outcome
• injury-prevention software

If you have a medical condition, an injury, or are pregnant, consult a qualified professional before training to a target pace produced by the app. You are solely responsible for how you train and race.

4. Eligibility

You must be at least 13 years old to use rox-strat. If you are under the age of majority in your jurisdiction, you must have permission from a parent or guardian.

5. Account & access

Access to rox-strat requires Sign in with Apple. Your Apple ID is managed by Apple — we do not store or have access to your Apple ID credentials. You are responsible for keeping your device and Apple ID secure.

6. rox-strat Pro subscription

rox-strat Pro is an auto-renewing in-app subscription that unlocks premium features (the ML decay engine, the live readiness score, Strava sync, fatigue sliders, and the CrossFit converter).

• Payment is charged to your Apple ID at confirmation of purchase.
• The subscription renews automatically unless you cancel at least 24 hours before the end of the current period.
• You can manage or cancel anytime in App Store → your account → Subscriptions.
• Refunds are handled by Apple under the App Store refund policy — we cannot issue refunds directly.
• Free trials, if offered, convert to a paid subscription unless cancelled before the trial ends.

7. Third-party services

The app interacts with the following services when you explicitly enable them:

• Apple Health (HRV, sleep, workouts) — governed by your HealthKit permissions.
• Strava — governed by Strava's terms of service.
• RevenueCat — used to verify subscription state. Their terms and privacy policy apply.

We are not responsible for the availability, accuracy, or content of these third-party services.

8. Acceptable use

You agree not to:

• reverse-engineer, decompile, or attempt to extract the source code of the app
• tamper with the in-app purchase verification flow
• use the app to harass, defame, or impersonate others
• use the app in connection with any commercial coaching, race-pacing, or wagering service without our written consent

9. HYROX® trademark

rox-strat is not affiliated with, endorsed by, sponsored by, or otherwise associated with HYROX® or Hyrox World GmbH. HYROX® is a registered trademark of Hyrox World GmbH. References to HYROX® race format, stations, or race-day mechanics are used for descriptive purposes only.

10. Intellectual property

The app, its source code, design system, ML models, brand assets, and copy are owned by the rox-strat team. Limited, personal, non-commercial use of the app on your own iOS device(s) is permitted under these terms.

11. Warranty disclaimer

The app is provided "as is" and "as available," without warranty of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the app is error-free, uninterrupted, or that pacing estimates will be accurate for any particular athlete on any particular day.

12. Limitation of liability

To the maximum extent permitted by law, the rox-strat team is not liable for indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or athletic performance, arising out of your use of the app. Direct liability, if any, is limited to the amount you paid for rox-strat Pro in the twelve months preceding the claim.

13. Changes to these terms

We may update these terms. Material changes will be noted on this page and the "Last updated" date will move. Continued use of the app after a change constitutes acceptance.

14. Termination

You may stop using the app and delete it at any time. We may suspend or terminate access if you breach these terms.

15. Governing law

These terms are governed by the laws of the jurisdiction in which the rox-strat team is registered, without regard to conflict-of-laws principles. Mandatory consumer-protection laws in your country still apply.
