Terms of Service

Introduction

Welcome to FreeFlight (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at pararoll.com and all associated free-flight tools, calculators, and services (collectively, the “Service”).

By accessing or using our Service, you agree to be bound by these Terms. If you disagree with any part of these terms, then you may not access the Service.

Acceptance of Terms

By accessing, browsing, or using FreeFlight, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference.

We reserve the right to update or modify these Terms at any time without prior notice. Your continued use of the Service after any such changes constitutes your acceptance of the new Terms.

Informational Use & Verifying Results

FreeFlight provides estimates and general guidance for informational purposes only. Calculator results, general guidance bands, and technical information on the Service are informational and may be incomplete or not applicable to your specific equipment, and the Service is not a substitute for certified instruction, a manufacturer’s published specifications, or an in-person site and equipment assessment. Real flying conditions, equipment, and site behaviour depend on many factors. By accessing or using the Service, you agree to treat results as general informational content rather than a guarantee of results or a safety certification, and to verify anything that matters for your safety with a certified instructor, your equipment manufacturer, or your site’s own guidance before you fly. All content on this site is general informational content only and is NOT a substitute for certified paragliding or free-flight instruction; results vary.

Get Certified Instruction When It Matters

You are responsible for using your own judgment, and for seeking training and an in-person assessment from a certified instructor, before making decisions about flying, equipment, or a specific site or day’s conditions. Our tools are designed to assist and inform, not to replace certified instruction or your own judgment.

Tool Accuracy and Disclaimers

Calculation Accuracy

Our calculators and tools are provided for informational and educational purposes only. While we strive for accuracy, we cannot guarantee that all calculations will be error-free or suitable for your specific equipment or situation. Results are estimates based on standard formulas and widely-cited conventions and the figures you enter; actual outcomes may vary based on your specific equipment, conditions, and individual circumstances.

No Guarantee of Results

FreeFlight makes no warranties, expressed or implied, and disclaims all other warranties including implied warranties of merchantability, fitness for a particular purpose, or non-infringement of intellectual property or other violation of rights.

Safety-Related Decisions

Guidance on this site is general and informational only and is not a substitute for certified instruction, a manufacturer’s published specifications, or an in-person site and equipment assessment. Real flying conditions and equipment behaviour depend on many factors. Always treat results as general guidance, not a guarantee of safety or performance, use your own judgment, and get certified instruction and an in-person assessment before you fly.
