Safety summary
- Ignis is not a medical device and has no medical device certification.
- Ignis does not provide medical advice; measurements must not be used for diagnosis, treatment, or emergency decisions.
- Heart rate, HRV, SpO₂, blood pressure, respiratory rate, stress and emotion values are algorithm estimates, for wellness reference only.
- For emergency symptoms such as chest pain, difficulty breathing, or fainting, call your local emergency number immediately (e.g., 911 in the US, 120 in China) or go to a hospital.
- Consult a qualified physician for any health decision.
1. Nature of the measurements
- Ignis estimates physiological metrics from camera video using rPPG (remote photoplethysmography); the values are estimates, not direct measurements.
- Results vary with lighting, motion, camera quality, skin tone, facial occlusion, and makeup; individual differences are significant.
- Internal comparison-test error data (heart rate ±1–2 BPM at N = 348; blood pressure ±8 mmHg, SpO₂ ±2–4% and respiratory rate ±5–6% without a disclosed comparable sample size) is self-reported by the company and not third-party certified; see Technology Overview · Accuracy and Error.
- Blood pressure and SpO₂ estimates are not a substitute for blood pressure monitors, pulse oximeters, or other professional medical devices.
2. Not intended for
Ignis is not intended for, and must not be used as a basis for:
- Disease diagnosis, screening, treatment, or medication decisions;
- Emergency or urgent medical judgment;
- Medical, insurance, legal, or other legally binding evidence;
- Replacing the judgment of physicians, nurses, or other qualified medical professionals.
3. When to seek medical care
Seek professional medical help immediately (in China, call 120; in the US, call 911) if you experience:
- Chest pain, chest tightness, or persistent palpitations;
- Difficulty breathing, severe dizziness, fainting, or altered consciousness;
- Persistently abnormal SpO₂, blood pressure, or other metrics, especially with discomfort;
- Any symptom that worries you — regardless of what the device shows.
Remember: a device reading does not override how your body actually feels.
4. Data and privacy
- The camera is activated only when you explicitly start a measurement; measurement frames are transmitted over an encrypted connection to the analysis service to compute metrics in real time.
- Measurement history is stored locally on the user's client device by default; the web client separates it by account, while the Android app uses device-local storage; it is used for historical trends and can be cleared in Settings.
- Complete data processing rules are described in the Privacy Policy; for data-related questions, contact wuac@yanshutech.com.

6. Frequently Asked Questions (FAQ)
1. Can Ignis be used for medical diagnosis?
No. Ignis is not a medical device and holds no medical device certification. Its measurements are algorithm estimates for wellness reference only and cannot be used for diagnosis, treatment, or medication decisions. For health concerns, consult a qualified physician.
2. What should I do if a measurement looks abnormal?
Rest and measure again; do not make judgments or take medication based on a single reading. If the metric remains abnormal or you feel unwell, consult a physician or visit a medical institution. For emergency symptoms such as chest pain, difficulty breathing, or fainting, call your local emergency number immediately (e.g., 911 in the US, 120 in China).
3. Can measurement results be used as medical, insurance, or legal evidence?
No. Ignis results do not constitute medical records or legally valid evidence and cannot be used for medical diagnosis, insurance claims, or judicial purposes. For such scenarios, use certified medical devices and obtain conclusions from professional institutions.
