服務條款 / EULA

Effective: 1 June 2026 · Ignition Musictech Limited

Please read these Terms of Service ("Terms") carefully before using the Masternotes (大師說) app operated by Ignition Musictech Limited ("we", "us", "Company"). By downloading, installing, or using the app, you agree to be bound by these Terms. If you disagree, please don't use the app.

1. Eligibility

To use Masternotes, you confirm that: (a) you're at least 13 years old; (b) if you're between 13 and 15, your parent or guardian has reviewed these Terms and agreed on your behalf before you use the Service; (c) if you're 16 or over, you have the legal capacity to agree to these Terms yourself; and (d) your use complies with all laws in your jurisdiction.

Minimum age is 13. Users aged 13–15 require parental or guardian consent. Users under 13 may not use this Service.

2. What Masternotes Is

Masternotes is an AI-powered conversational app for classical music lovers. It gives you: natural-language conversations about composers, performers, and repertoire; AI responses drawn from a curated knowledge base; your personal conversation history; and an AI memory system that learns your musical preferences over time to give you better responses.

Masternotes is an AI app — you are always talking to artificial intelligence, not a human.

This notice is provided pursuant to Article 50(3) of the EU AI Act, which requires AI chatbots to be transparent about their AI nature (applicable from 2 August 2026). Our AI will always identify itself as AI if you ask.

The app is in active development. Features may be added, modified, or removed. We'll give you reasonable notice of material changes.

3. AI-Generated Content

Please read this section. It sets out important limits on what our AI can and can't do.

The app uses large language models — including OpenAI, Anthropic Claude, and Google Gemini — to generate responses. By using the app, you acknowledge:

1. AI responses may contain errors, inaccuracies, or outdated information. Always verify independently before making important decisions.
2. AI responses aren't professional music education, academic research, or expert advice.
3. The AI may reference or discuss copyrighted works for informational and educational purposes.
4. We make no warranty that AI responses are accurate, complete, or fit for any particular purpose.
5. The AI memory system automatically infers and stores facts about your musical preferences (see Privacy Policy Section 2.3). You can delete this data anytime.
6. We do not use your conversations to train AI models. Your messages are sent to our AI providers only to generate responses. See our Privacy Policy, Section 5.1.
7. You are always interacting with AI, not a human. Our AI will always identify itself as AI if you ask directly. (EU AI Act Art. 50(3), applicable from 2 August 2026.)

4. Your Account

4.1 Registration

You need an account to access the full app. Please provide accurate, up-to-date information when signing up and keep it current.

4.2 Account Security

You're responsible for keeping your login credentials secure and for all activity under your account. If you suspect unauthorised access, let us know immediately at legal-masternotes@igmusictech.com.

4.3 Sign in with Apple & Third-Party Login

Future versions may offer third-party login options. Per Apple's App Store guidelines, Sign in with Apple will always be available alongside any other social login on iOS.

5. Acceptable Use

You agree to use the app lawfully and in accordance with these Terms. You must not:

1. Use the app if you're under 13; or use the app between the ages of 13 and 15 without parental or guardian consent.
2. Reverse-engineer, decompile, or extract source code from the app or its AI models.
3. Use bots, scripts, or automated tools that place excessive load on the Service.
4. Circumvent or interfere with security features, rate limits, or access controls.
5. Use the app to generate, distribute, or facilitate harmful, defamatory, or illegal content.
6. Misrepresent AI-generated responses as your own original human-authored work in contexts where authorship matters (e.g. academic submissions, professional publications).
7. Violate any applicable laws or regulations in your jurisdiction.

6. Intellectual Property

6.1 Our IP

The app, its original content (excluding User Content and AI-generated responses), features, branding, and underlying technology belong to Ignition Musictech Limited and are protected by copyright, trademark, and other IP laws.

6.2 Your Content

You own the content you put into the app ("User Content"). By submitting User Content, you give us a limited, worldwide, non-exclusive licence to process, store, and use it solely to provide and improve the Service.

6.3 Music & Copyright

The app discusses and analyses classical music works, composers, and performances for informational and educational purposes. Factual information about music — dates, instrumentation, historical context, biographical facts — is not protected by copyright. AI responses that reference musical works do so within the scope of commentary and educational discussion.

6.4 AI-Generated Responses & Ownership

AI-generated responses in Masternotes belong to you. You can use them for your own personal purposes. We make no ownership claim over what the AI generates for you.

However, there are two important caveats: first, AI outputs are not exclusively yours in a copyright sense — similar or identical responses may be generated for other users asking similar questions, and we make no warranty of uniqueness. Second, you agree not to present AI-generated responses as your own original human-authored work in contexts where authorship is material (for example, academic submissions, professional publications, or anywhere claims of human authorship would be relevant).

6A. Third-Party Content & Copyright

6A.1 How We Build Our Knowledge Base

Our editorial team compiles and maintains the knowledge base. Our approach:

1. Original writing: The vast majority of our knowledge base is original content written by our team based on their expertise. Facts, historical information, musical analysis, and educational content about classical music are not copyrightable and may be freely expressed in original language.
2. Limited quotation: Where we quote third-party sources, we use only brief excerpts for illustration or attribution purposes. We never reproduce substantial portions of any copyrighted work.
3. Source attribution: All third-party sources include a reference link to the original material so users can consult the primary source.

6A.2 YouTube Content

The app may display YouTube videos using the official YouTube embedded player provided by YouTube/Google. This is expressly permitted by YouTube's Terms of Service and the YouTube API Services Terms. We do not download, copy, or host any YouTube content on our own servers. Any knowledge in the app derived from YouTube videos — such as statements by musicians or educators — represents our team's original understanding and expression of that subject matter, not a reproduction of the video's audio or transcript.

6A.3 Written Sources & Public Domain

Our use of written sources follows these principles:

1. Public domain works: Works whose copyright has expired (generally, works by authors who died more than 50 years ago under Hong Kong law, or as determined by the relevant jurisdiction) may be quoted freely. We make reasonable efforts to verify public domain status before extensive use.
2. Copyrighted works: For works still under copyright, we rely on brief quotation for the purpose of commentary, criticism, and education — constituting fair dealing under the Hong Kong Copyright Ordinance (Cap. 528) and analogous provisions in other jurisdictions.
3. Source links: All quoted or referenced materials are accompanied by a link to the original source.

6A.4 Wikipedia Content

When a query can't be answered from our knowledge base, the AI may retrieve supplementary information in real time from Wikipedia via the Wikimedia Foundation's public API. The following applies:

1. Wikipedia content is made available under CC BY-SA 4.0 and the GNU Free Documentation Licence (GFDL).
2. The app attributes Wikipedia as the source and provides a direct link to the relevant article whenever Wikipedia content is displayed.
3. Displaying Wikipedia content does not constitute our endorsement of its accuracy. Wikipedia is user-generated and may contain errors.
4. Use of the Wikipedia API is subject to Wikimedia Foundation Terms of Use (foundation.wikimedia.org/wiki/Terms_of_Use).

6A.5 Third-Party Links

The app may provide links to third-party websites or resources for reference. We don't control, endorse, or take responsibility for the content, privacy practices, or availability of those resources.

6A.6 Copyright Infringement Claims

If you believe content in the app infringes your copyright, contact us with: (a) identification of the copyrighted work; (b) identification of the specific infringing content in the app; (c) your contact information; (d) a statement that you have a good faith belief the use is not authorised.

Send copyright notices to: legal-masternotes@igmusictech.com. We will review and respond within 14 business days, and remove or modify content found to be infringing.

3. EU/EEA consumers: you may have a statutory 14-day right of withdrawal for digital content not yet accessed. Email legal-masternotes@igmusictech.com to exercise this right.
4. Free tier: no payment means no refund applicable.

8. Disclaimers

The app is provided "as is" without warranties of any kind. To the maximum extent permitted by applicable law, we disclaim all warranties — express or implied — including any implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

We don't warrant that: (a) the app will be uninterrupted, error-free, or secure; (b) AI responses will be accurate, complete, or reliable; or (c) the app will meet your specific needs.

9. Limitation of Liability

To the maximum extent permitted by applicable law, Ignition Musictech Limited, its directors, employees, and agents will not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the app — including loss of profits, data, goodwill, or other intangible losses.

Our total liability to you for any claim relating to these Terms or the app will not exceed the greater of: (a) the amount you paid us in the 12 months before the claim; or (b) HKD 100.

Nothing in these Terms limits liability for death or personal injury caused by negligence, fraud, or any liability that cannot be excluded by law.

10. Account Deletion & Termination

You can delete your account at any time through the app settings. Once deleted, your data will be permanently erased in accordance with our Privacy Policy.

We may suspend or terminate your access if you breach these Terms, engage in illegal activity, or cause harm to other users or us. We'll give you reasonable notice where possible.

11. Apple App Store — Required Terms

The following terms are required by Apple for all apps distributed on the App Store.

13. Updates to These Terms

We may update these Terms from time to time. For material changes, we'll give you at least 14 days' notice via in-app notification or email.

Severability: If any provision is found invalid or unenforceable, the remaining provisions continue in full force.

Entire Agreement: These Terms, together with our Privacy Policy, form the complete agreement between you and us about the app.
