Terms of Use

Last updated: November 2026

These terms apply to your use of harmonu.com ("Harmonu", "we", "us"). By using the site you agree to them. If you do not agree, please do not use the site.

1. The service

Harmonu provides free online tuners for musical instruments. You can tune with your microphone or by listening to reference tones. The service is provided free of charge for informational and educational musical purposes.

2. Tuning accuracy

We work to make the tuners accurate, but results depend on your device, its microphone, background noise and your instrument. The tuners are not a substitute for professional equipment or a professional technician. Tune carefully: tightening a string too far can break it or damage the instrument, and you are responsible for how you tune.

3. Microphone and your device

The microphone is used only if you allow it in your browser, and only to detect pitch on your device. See our Privacy Policy for details. You are responsible for your own device, browser and internet connection.

4. Acceptable use

When using Harmonu, you agree not to:

  • use the site for anything unlawful;
  • interfere with or overload the site, or try to gain unauthorised access to it;
  • send automated bulk requests or scrape the site at a scale that affects other users;
  • copy the site and present it as your own.

5. Intellectual property

The Harmonu name, logo, design, text, drawings and software belong to us or are used with permission. You may use the site for your own personal, non-commercial use, and you are welcome to link to it. Other use needs our written permission.

6. Links and third-party services

The site may link to or use services from third parties, such as analytics. We are not responsible for their content or practices, and their own terms and policies apply.

9. Limitation of liability

To the extent permitted by law, we are not liable for any indirect or consequential loss, or for any damage arising from your use of the site, including broken strings, damage to instruments or devices, or loss of data. Nothing in these terms limits liability that cannot be limited by law, including your rights as a consumer.

10. Governing law

These terms are governed by the laws of Morocco, and the competent Moroccan courts will handle any dispute.

11. Changes to these terms

We may update these terms from time to time. The date at the top shows when they were last changed. Continuing to use the site after a change means you accept the updated terms.
