Terms of Use
These terms govern your use of the MusicBall app ("the App"), published by Tinuv ("we", "us"). By downloading or using the App you agree to them. If you do not agree, please do not use the App.
Because the App is distributed through the Apple App Store, Apple's Licensed Application End User License Agreement also applies. Where these terms and Apple's standard EULA conflict, Apple's EULA governs.
1. Licence
We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on Apple-branded devices you own or control, in accordance with the App Store Terms of Service. You may not copy, redistribute, sell, rent, sublicense, reverse-engineer, decompile or attempt to derive the source code of the App, except to the extent that applicable law expressly permits it despite this restriction.
2. Your content
MIDI files you import remain entirely yours. We claim no ownership over them and never receive a copy — they are stored only on your device.
You are responsible for having the right to use any file you import. Do not import material you are not licensed to use. If your MIDI file is protected by copyright, the visualisations the App generates from it may be treated as derivative works in your jurisdiction; whether you may publish or share them is your responsibility to determine.
3. Included pieces
The App ships with seven pieces of classical music whose compositions are in the public domain, using MIDI transcriptions published under a Public Domain dedication by the Mutopia Project. They are provided for use within the App.
4. Screen recordings and sharing
You are welcome to record, stream and publish footage of the App running — including monetised video — provided the underlying music is yours to use. No attribution is required, though it is always appreciated.
5. No warranty
The App is provided "as is" and "as available", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that every MIDI file will produce a solvable machine — some scores are too dense or too sparse for the solver, and the App will tell you so.
6. Limitation of liability
To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or any loss of data, profits or goodwill, arising out of your use of or inability to use the App. Our total aggregate liability shall not exceed the amount you paid for the App.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for incidental or consequential damages. In those jurisdictions, the exclusions and limitations above apply only to the extent permitted, and nothing in these terms limits your statutory consumer rights.
7. Privacy
The App collects no data. See the Privacy Policy.
8. Changes
We may update these terms from time to time. The current version is always at this address with its "Last updated" date. Continuing to use the App after a change means you accept the revised terms.
9. Termination
This licence remains in effect until terminated. It ends automatically if you breach these terms, and you may end it at any time by deleting the App from your devices.
10. Governing law
These terms are governed by the laws of the jurisdiction in which we operate, without regard to conflict-of-law rules. This does not deprive you of the protection of mandatory consumer law in your country of residence.
