If you are under the age of majority in your jurisdiction, you must have permission from a parent or legal guardian to use the App.

4. User Account

The App does not require user registration or account creation. No personal account information is collected or stored by us.

5. License Grant and Restrictions

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the App on a compatible device that you own or control, solely for your personal purposes.

6.2 Feedback

Any feedback, suggestions, or ideas you provide regarding the App may be used by us without any obligation to you.

7. Conversion Accuracy and Disclaimer

7.1 Unit Conversions

The App performs unit conversions using standard conversion factors and mathematical formulas. Conversion accuracy depends on:

  • The mathematical precision limits of floating-point representation
  • The conversion factors defined in the App
  • Rounding behavior inherent to digital computation

7.2 Not a Certified Tool

THE APP IS INTENDED FOR GENERAL REFERENCE AND EVERYDAY USE. IT IS NOT A CERTIFIED OR VERIFIED PRECISION MEASUREMENT TOOL. DO NOT RELY ON THE APP FOR:

  • Professional engineering, scientific, or industrial calculations requiring certified precision
  • Safety-critical conversions where inaccuracy could result in injury or property damage
  • Medical dosage conversions or any health-related measurements
  • Any application requiring guaranteed accuracy beyond standard floating-point precision

7.3 Temperature Conversions

Temperature conversions use formula-based computation (with Celsius as the intermediate unit) due to the offset nature of temperature scales. While this method is mathematically standard, users should verify results when precision is critical.

7.4 User Responsibility

You are solely responsible for:

  • Verifying the accuracy of all conversions using appropriate professional tools when precision is critical
  • Any decisions or actions taken based on the App's conversion results
  • Understanding the limitations of floating-point arithmetic

WE EXPRESSLY DISCLAIM ALL LIABILITY FOR ANY DAMAGES, INJURIES, OR LOSSES ARISING FROM RELIANCE ON THE APP'S CONVERSIONS.
