Mezzo — Terms of Service
1Acceptance
By downloading, installing, or using Mezzo (the "App"), you agree to these Terms of Service ("Terms"). If you do not agree, do not use the App. These Terms form a legal agreement between you and the App's developer ("Mezzo," "we," "our").
These Terms apply alongside Apple's standard end-user license agreement (the Apple Standard EULA). Where any term in these Terms conflicts with the Apple EULA, the Apple EULA controls only to the extent of the conflict; otherwise, both apply.
2Eligibility
You must be at least 18 years old to use the App. If you are under 18, do not use the App.
The App is intended for personal, non-commercial use by adults seeking voice training for everyday speaking. It is not intended for medical or therapeutic purposes (see Section 8).
3The Service
Mezzo is a voice training application that:
- Records short audio samples of you reading aloud
- Analyzes pitch and related acoustic properties on your device
- Classifies your voice into one of six descriptive archetypes
- Delivers a six-week reading-and-reflection program with daily passages, focus prompts, and weekly written reflections
- Schedules optional local notifications for the weekly Sunday letter
The App's analysis is a calibrated heuristic based on pitch detection. It is not a clinical voice assessment, not a singing-instruction tool, and not a substitute for working with a qualified voice teacher, speech-language pathologist, or otolaryngologist.
We may add, change, or remove features over time. Substantive changes will be reflected in App Store updates and, where they affect your use of the App, in these Terms.
4Subscriptions and payments
The App offers paid subscriptions (currently $12.99 per week and $59.99 per year) and a one-time lifetime purchase ($99.99). Prices may change; current prices are displayed in the App at the moment of purchase.
All payments are processed by Apple through your App Store account. We never see your payment details. Subscriptions auto-renew at the displayed price for the displayed period until cancelled. You may cancel at any time:
- In the App: Profile → Subscription → MANAGE
- On iOS: Settings → [your name] → Subscriptions → Mezzo
Cancellations take effect at the end of the current billing period. We do not issue partial refunds; refund requests are handled by Apple under Apple's published refund policy.
Restoring purchases: tapping "— restore purchase —" on the paywall consults Apple for any prior purchase associated with your Apple ID and reactivates your entitlement if one is found.
The lifetime purchase is a one-time, non-recurring transaction that grants ongoing access to the App's then-available features for as long as the App is supported on your device's operating system.
5Free use
The App can be installed and explored without subscribing. The voice analysis (baseline reading + reveal) is available before any purchase is required. The six-week program, Sunday letters, weekly audits, and free-practice mode require an active subscription or the lifetime purchase.
6Acceptable use
You agree not to:
- Decompile, reverse-engineer, or otherwise attempt to derive the App's source code or pitch-analysis logic, except where that right cannot be excluded by law
- Use the App in a way that violates applicable law or another person's rights
- Misrepresent your identity or your subscription status to obtain features or pricing you have not paid for
- Modify, distribute, sublicense, lease, sell, or otherwise transfer the App to any third party
7Intellectual property
The App. The App, its design, the six-archetype taxonomy, the curriculum structure, the editorial copy (passages aside, see below), the Sunday letters, the cohort observations, the brand marks, and all related software are the intellectual property of the developer and its licensors. We grant you a personal, limited, non-transferable, non-exclusive license to use the App on iOS devices you own or control, for the duration of your subscription or lifetime entitlement.
Reading passages. All reading passages used in the App are sourced from works in the public domain (pre-1929 publication date). Source provenance is recorded in the App's curriculum metadata.
Your content. Voice recordings, your name, your reflections, and your archetype results are yours. They are stored only on your device. We do not claim any rights in them, and we do not access them.
8Health and medical disclaimer
The App is a self-directed reading-and-reflection program. It is not medical advice, not voice therapy, and not a substitute for professional voice training, speech therapy, or medical evaluation.
If you experience hoarseness, vocal fatigue, pain, or other symptoms that persist or worsen, stop using the App and consult a qualified medical professional. The App does not diagnose, treat, or cure any condition.
Vocal exercises, like any physical activity, carry some risk. You use the App at your own risk and assume responsibility for any outcomes.
9No warranty
The App is provided "as is" and "as available" without warranties of any kind, whether express, implied, statutory, or otherwise, to the maximum extent permitted by law. We do not warrant that the App will be uninterrupted, error-free, secure, or that the analysis results will meet your expectations.
Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions, the exclusions in this Section apply only to the maximum extent permitted by law.
10Limitation of liability
To the maximum extent permitted by law, the developer's total aggregate liability arising from or relating to the App or these Terms shall not exceed the greater of (a) the amount you paid the developer in the 12 months before the event giving rise to the claim, or (b) USD $50.
In no event shall the developer be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, including loss of profits, loss of data, or loss of goodwill, even if advised of the possibility of such damages.
Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages; in those jurisdictions, the limitations in this Section apply only to the maximum extent permitted by law.
11Indemnification
You agree to indemnify and hold harmless the developer from any claim, loss, liability, or expense (including reasonable legal fees) arising from your use of the App in violation of these Terms or applicable law.
12Termination
You may stop using the App at any time. To delete all data stored by the App, delete the App from your device.
We may suspend or terminate your access to the App if you materially breach these Terms or applicable law. On termination: your license to use the App ends; your right to access paid features ends; data already stored on your device remains under your control until you delete the App.
13Apple
You acknowledge and agree that:
- These Terms are between you and the developer, not between you and Apple. Apple is not responsible for the App or its content.
- Apple has no obligation to provide maintenance or support for the App.
- In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
- The developer, not Apple, is responsible for addressing any claims relating to the App, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims arising under consumer protection or similar legislation.
- The developer, not Apple, is responsible for the investigation, defense, settlement, and discharge of any third-party intellectual property claim that the App or your use of it infringes that third party's intellectual property rights.
- Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple has the right (and is deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
14Changes to these Terms
We may update these Terms from time to time. The effective date at the top reflects the most recent revision. If a change materially affects your rights or obligations, we will notify you within the App before the change takes effect. Continued use of the App after the effective date of revised Terms constitutes acceptance of those Terms.
15Governing law
These Terms are governed by the laws of the Republic of Indonesia, without regard to its conflict-of-laws principles. Any dispute arising from or relating to these Terms or the App shall be resolved in the courts of Indonesia, except where applicable consumer-protection law gives you the right to bring proceedings in your country of residence.
If you live in the European Union, the United Kingdom, or another jurisdiction whose mandatory consumer-protection law overrides this clause, that mandatory law applies in your case.
16Severability
If any provision of these Terms is found unenforceable, the remaining provisions remain in full force.
