Terms of Use

Effective 5 September 2026

These terms govern your use of the Clefly app and this website, both operated by Triton IT ("we", "us"), based in the Netherlands. By downloading or using Clefly you agree to them.

1. The service

Clefly is an educational app that teaches music notation reading. The current version is free to download and use, with no ads and no in-app purchases. Clefly needs an account: you sign in with Apple the first time you open the app, so that your learning progress can be backed up and restored on any device you use. We may add optional paid features in a future version; anything you would have to pay for will always be clearly marked before you are charged.

2. License

We grant you a personal, non-exclusive, non-transferable license to use Clefly on Apple devices that you own or control, for your own learning. You may not copy, modify, distribute, sell, rent, reverse-engineer, or create derivative works of the app or its content, except where law expressly permits it.

3. Intellectual property

The app, its design, lessons, exercises, artwork, and the Clefly name are owned by us or our licensors and are protected by intellectual-property law. These terms do not grant you any rights to them beyond the license above.

4. Acceptable use

Use Clefly as intended: as a learning tool. Do not attempt to disrupt, probe, or gain unauthorized access to the app, its analytics infrastructure, or this website.

5. Your progress data

Your learning progress is kept in the app and backed up to your Clefly account on our servers, so that signing in on a new device restores it. Deleting the app removes the copy on that device; the backup stays with your account until you delete the account, which you can do at any time in the app under Profile, Settings. Deleting your account also deletes the backup. We make reasonable efforts to keep the backup available and intact, but we do not guarantee that it will always be available or free of loss, so please treat it as a convenience rather than an archive. See the Privacy Policy for details on what we store and why.

6. No warranty

Clefly is provided "as is" and "as available". We work hard to make it accurate and reliable, but we do not warrant that it will be uninterrupted, error-free, or that it will produce a particular learning outcome. Nothing in these terms limits any warranty that applies to you as a consumer by mandatory law.

7. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, or consequential damages arising from your use of the app. Our total liability for any claim related to the app is limited to the amount you paid for it in the twelve months before the claim (for the free app, that is zero). This limitation does not apply to damage caused by our intent or gross negligence, or where consumer law does not allow it.

8. App Store

Clefly is distributed through Apple's App Store. Apple's own terms and Apple's standard Licensed Application End User License Agreement also apply to your download. Apple is not responsible for the app or its content and has no obligation to provide support for it.

9. Changes

We may update the app and these terms. If we make material changes to the terms, we will update the date at the top of this page. Continuing to use the app after a change means you accept the updated terms.

10. Governing law

These terms are governed by the laws of the Netherlands. Disputes will be brought before the competent court in the Netherlands, unless mandatory consumer law lets you choose the courts of your own country of residence.
