These Terms are a legal agreement between you and Ammar Software B.V. ("Crusd," "we," "us," or "our"), a private limited company (besloten vennootschap) registered in the Netherlands under Chamber of Commerce (KvK) number 91771757, which operates the App and the Website. If you do not agree to these Terms, do not use the App or Website.
2. Description of Service
Crusd is an iOS application that provides structured training plans for running, strength, and conditioning. The App offers workout tracking, training load analysis, Apple Watch integration, calendar sync, and optional readiness-based workout adaptation through health data analysis.
3. Eligibility
You must be at least 13 years of age to use Crusd. By using the App, you represent and warrant that you are at least 13 years old and have the legal capacity to enter into these Terms. If you are under 18, you represent that your parent or legal guardian has reviewed and agreed to these Terms.
4. Health & Fitness Disclaimer
Crusd is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or medical condition.
Always consult a physician or qualified healthcare provider before beginning any exercise program, particularly if you have any pre-existing medical conditions, injuries, or health concerns.
The readiness scores, adaptive insights, training recommendations, and recovery suggestions provided by Crusd are generated algorithmically based on available health data (including heart rate variability, resting heart rate, sleep analysis, and training load). These outputs should not be considered medical advice and are not a substitute for professional medical judgment.
You acknowledge and agree that:
- Physical exercise carries inherent risks, including but not limited to risk of physical injury, disability, and death, and you voluntarily assume all such risks associated with your use of the App.
- Crusd does not guarantee any specific fitness outcomes, performance improvements, or health results.
- You are solely responsible for determining whether any training plan, workout, or recommendation provided by the App is appropriate for your individual fitness level, health status, and circumstances.
- If you experience any pain, discomfort, dizziness, or other symptoms during exercise, you should stop immediately and consult a healthcare provider.
- The training plans provided by Crusd are general fitness programs and are not customized medical prescriptions.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL CRUSD BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE APP.
CRUSD'S TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR YOUR USE OF THE APP SHALL NOT EXCEED THE AMOUNT YOU PAID TO CRUSD IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES. IN SUCH JURISDICTIONS, CRUSD'S LIABILITY SHALL BE LIMITED TO THE GREATEST EXTENT PERMITTED BY LAW.
14. Indemnification
You agree to indemnify, defend, and hold harmless Crusd and its officers, directors, employees, and agents from any claims, damages, liabilities, costs, and expenses (including reasonable attorney's fees) arising out of or related to your use of the App, your violation of these Terms, or your violation of any rights of another.
15. Modifications to Terms

18. Severability
If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary so that these Terms shall otherwise remain in full force and effect.
