Vitals DiaryTerms of Use
Effective date: July 12, 2026
1. Acceptance
By downloading or using Vitals Diary (the “App”), you agree to these Terms of Use and to Apple's standard Licensed Application End User License Agreement. If you do not agree, please do not use the App.
2. What the App does
The App lets you record blood pressure, heart rate, blood glucose and related notes, set reminders, view trends of your own entries, and generate PDF reports of your records. It can also measure your heart rate using the phone's camera and flash, and — if you connect it — read blood pressure, heart rate and blood glucose from Apple Health or Health Connect so you do not have to type them in again.
The camera heart rate measurement is not a medical device. It records a number for your own records only, and carries no medical meaning. It is not a substitute for a measurement taken with a medical instrument, and it must not be relied on for any medical decision.
All comparisons shown (such as “above the target you set”) are factual comparisons against values you set yourself and carry no medical meaning.
3. Subscriptions and purchases
- Premium features are available via monthly or annual auto-renewing subscriptions, or a one-time lifetime purchase, billed through your Apple account.
- Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your device's subscription settings.
- Free-trial periods, if offered, convert to a paid subscription unless cancelled before the trial ends.
- Refunds are handled by Apple under Apple's policies.
4. Lifetime purchase — scope
The lifetime purchase permanently unlocks all on-device features of the App (trends, PDF reports, full history, and future on-device premium features). Optional online services that may be offered in the future (such as cloud sharing) are add-on services: if such a service is ever discontinued, on-device features — your diary, charts, history and reports — remain fully functional. Your data lives on your device and does not depend on our servers.
5. Your responsibilities
- Enter data accurately; the App displays what you enter.
- Keep your device and its backups secure; the App's data lives on your device.
- Do not use the App where its failure could lead to injury — it is a diary, not a monitoring or alerting system.
6. Intellectual property
The App, its design and branding are owned by the developer. These terms do not grant you any right to use them except as needed to use the App.
7. Disclaimer and limitation of liability
The App is provided “as is” without warranties of any kind. To the maximum extent permitted by law, we are not liable for any indirect, incidental or consequential damages arising from use of the App. Nothing in these terms excludes liability that cannot be excluded by law.
8. Changes
We may update these terms; material changes will be noted in the App's release notes. Continued use after a change constitutes acceptance.
9. Governing law
These terms are governed by the laws of Taiwan (R.O.C.), without regard to conflict-of-law rules. Mandatory consumer protections of your country of residence remain unaffected.
