1. Acceptance and scope
By downloading, accessing, or using Sumvia, you agree to these terms and the Privacy Policy. If you do not agree, do not use the app or website. You must be old enough to accept these terms where you live; otherwise a parent or guardian must agree and supervise your use.
Sumvia supports health calculations, information understanding, and personal records for personal, non-emergency reference.
2. Health-reference boundary
Sumvia’s results and content do not constitute a medical diagnosis, treatment recommendation, prescription, prognosis, or emergency advice. They cannot replace assessment or advice from a qualified professional.
If you feel unwell, see an unusual result, have a medication or pregnancy-related question, or have another health concern, consult a qualified professional. If you believe you or another person may face an emergency, contact local emergency services immediately. Do not rely on the app for emergency decisions.
3. Your responsibility for inputs and results
Results depend on the data you enter, the units you select, and the calculator’s assumptions. Check your inputs, units, and context before using a result.
Reference ranges can vary with age, sex, individual background, measurement method, and source. A single result should not be used by itself to make a medical decision.
4. Limited license and Prohibited conduct
Subject to these terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to use the app on supported devices.
You may not use it unlawfully; interfere with security or operation; bypass access restrictions; impersonate the official service; use content to mislead others; or, except where the law permits, reverse engineer, copy, rent, sell, or redistribute the app or its content.
5. Features and availability
We work to keep content clear and resolve known issues, but features, sources, and reference ranges may change or be unavailable for a device, OS version, or region. The current in-app display is the source of truth for the available tool set.
6. Sharing and third-party services
When you use the system share sheet to send content to a third-party app or service, that destination is responsible for subsequent processing. Review its terms and privacy policy before use. We do not control or promise the content, availability, or data practices of third-party services.
7. Content and identity
Sumvia, 得数, the app icon, interface design, and original site content are protected under applicable law. The limited license transfers no ownership or intellectual-property rights.
8. Disclaimer and Limitation of liability
Disclaimer: To the maximum extent permitted by applicable law, the app and website are provided “as is” and “as available.” We do not warrant that calculations are error-free, complete, continuously available, or suitable for your specific health, clinical, or other purpose.
Limitation of liability: To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, special, or consequential loss arising from use or inability to use the app, reliance on results, input errors, or third-party services. Nothing here excludes liability or consumer rights that cannot legally be excluded.
9. Governing law and disputes
The publisher and its location are not confirmed in this repository, so this page does not name a governing law, court, or arbitration venue. The publisher must complete this section before launch without limiting non-waivable consumer rights where a user lives.
10. Changes and termination
We may update these terms to reflect product features or applicable requirements and will show a new effective date here. If you materially breach these terms, we may terminate the limited license where law permits. You may stop using and uninstall the app at any time.
11. Contact
Questions about these terms can be sent to . Do not send sensitive health information through ordinary email. The publisher must verify this mailbox and domain before launch.
