Terms of Service

Last updated: August 3, 2026

Introduction

Welcome to HandDrumHub (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at drukn.com and all associated percussion 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 HandDrumHub, 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

HandDrumHub provides estimates and tools for general guidance and informational purposes only. Calculator results, tuning guidance, and technical information on the Service are informational and may be incomplete or not apply to your specific instrument, and the Service is not a substitute for advice from a luthier, instrument-repair professional, or experienced teacher. Head material, shell construction, and environmental conditions all affect real-world outcomes. By accessing or using the Service, you agree to treat results as general informational and educational content rather than a guarantee of a given pitch, tension, fit, or timing, and to verify any figure that matters against your specific instrument and your own ear before cutting a head, re-tensioning ropes, or making a repair. All content on this site is general informational and educational content only and is NOT professional tuning, instrument-repair, or hearing-safety advice; results vary.

Description of Service

HandDrumHub provides free, practical percussion tools and educational resources, including:

All tools are provided free of charge. We reserve the right to modify, suspend, or discontinue any part of the Service at any time.

User Responsibilities

Appropriate Use

Users of our tools and website agree to:

Check With a Professional When Needed

You are responsible for using your own judgment, and for seeking advice from a luthier, repair professional, or experienced teacher, before making irreversible changes to an instrument such as cutting a head or re-tensioning ropes. Our tools are designed to assist and inform, not to replace professional advice or your own ear and 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 instrument. Results are estimates based on standard acoustic formulas and industry conventions and the figures you enter; actual outcomes may vary based on your specific instrument, materials, and environment.

No Guarantee of Results

HandDrumHub 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.

Tuning & Repair Decisions

Tuning guidance is general and informational only and is not a substitute for advice from a luthier, repair professional, or experienced teacher. Instrument materials, construction, and condition depend on many factors. Always treat results as general guidance, not a guarantee of a given outcome, use your own judgment and ear, and consult a professional before a repair or an irreversible change to a valuable instrument.
