6. Accuracy Disclaimer

All calculated times are mathematical estimates based on linear velocity models. Real-world performance is affected by many variables including but not limited to fatigue, weather, surface, technique, and individual physiology. SprintCalc makes no guarantees regarding the accuracy or applicability of any calculated result.

7. Assumption of Risk

Athletic training involves inherent physical risks. By using this App, you acknowledge and accept those risks. SprintCalc, its developers, and affiliates are not liable for any injury, illness, or other harm that may result from training based on the App's output.

8. Data Deletion

If you choose to delete your account or saved data within the App, please note that all saved times, preferences, and history will be permanently erased and cannot be recovered. Make sure to export or record any data you wish to keep before deletion.

9. App Name & Trademark

The name "SprintCalc" is used for this application. Users are advised to verify independently that any training program name they associate with this tool does not infringe on existing trademarks. We recommend searching your app or program name before widespread use to avoid potential trademark conflicts.
