FAQs

🔒 Privacy & Data Security

Q1: Where is my health data stored?
A: All data stays exclusively on your iPhone or Apple Watch. Nothing is sent to clouds, servers, or third parties. Even we (the developers) cannot access your information.

Q2: Does the app require internet access?
A: No. Lume works 100% offline. Internet is only needed for downloading the app or viewing this website.

Q3: What permissions does Lume need?
A: Only what you grant:

• Apple Health (optional): To read/write steps, heart rate, or sleep data.

• Notifications: For reminders (hydration, alarms).

• No contacts, location, or identity access.

Q4: If I uninstall Lume, is my data deleted?
A: Yes. All data is permanently erased from your device when uninstalled.

📱 Features & Functionality

Q5: Which devices are supported?
A: iPhone (iOS 16+) and Apple Watch (WatchOS 9+). No Android or web version exists.

Q6: Can I use Lume without Apple Health?
A: Yes! Manually log blood pressure, temperature, water intake, etc. Heart rate/HRV require Apple Watch or Health access.

Q7: How accurate are stress/HRV readings?
A: They align with Apple Watch’s sensor precision. For medical diagnoses, consult a professional. Lume is a wellness tool, not a medical device.

Q8: Does the AI chatbot work offline?
A: Absolutely. All chat suggestions are generated on-device using private AI—no data leaves your phone.

Q9: Can I sync data between iPhone and Apple Watch?
A: Yes! Via Apple’s native Bluetooth sync. Lume doesn’t handle this—it’s managed securely by Apple.

⚙️ Technical Support

Q10: Why isn’t my heart rate/stress updating?

• Ensure Apple Health permissions are enabled (Settings > Privacy > Health > Lume).

• Restart your Apple Watch.

• Wear your watch snugly during measurements.

Q11: How do I reset goals or data?
A: Go to Settings > Data Management > Clear Goals/History within the app.

Q12: Does Lume drain battery?
A: Minimal impact. Background heart rate/HRV monitoring uses Apple Watch’s optimized sensors.

💳 Purchases & Accounts

Q13: Is Lume free?
A: The core app is free. Optional premium features (e.g., advanced AI diet plans) require a one-time purchase. No subscriptions.

Q14: Do I need an account?
A: No. Lume has zero sign-ups, logins, or profiles. Your device is your account.

🩺 Health & Medical

Q15: Can Lume replace my doctor?
A: No. It’s a wellness tracker, not a medical device. Always consult professionals for health concerns.

Q16: Why does Lume track blood pressure if Apple Watch doesn’t natively support it?
A: For manual logging. If you own a compatible Bluetooth BP monitor, pair it with Apple Health—Lume can read that data.

A: No. We focus exclusively on delivering a private, optimized experience for Apple users.
