FAQ
Straight answers about accounts, AI, Health, and privacy.
When does LunaFit launch?
LunaFit is coming soon on iOS. Follow @lunafit.app or join the email waitlist for launch notification.
Is LunaFit free?
You can start with core logging. Optional Plus / Pro AI plans unlock more AI credits. Purchases are billed through Apple; manage or cancel in iOS Settings → Apple ID → Subscriptions.
How does the AI coach work?
When you use coach chat or meal parsing, requests go through LunaFit’s servers to model providers. AI features consume account credits and may be inaccurate — always review suggestions before acting.
Does LunaFit use Apple Health?
Health access is optional. LunaFit can read active/resting energy on-device for calorie-gap estimates, and may read menstrual flow if you choose to import cycle history. You control permissions in iOS Settings → Health → Data Access & Devices → LunaFit.
Is cycle tracking required?
No. Cycle features are optional for people who track their period. Everyone gets diet, workout, and AI coaching tools without enabling cycle tracking.
How do I export or delete my data?
Signed-in users can export or delete their account from Profile in the app, or contact support@lunafit.app. See our Privacy Policy.
Is this medical advice?
No. LunaFit is for fitness and nutrition tracking only — not a medical device and not medical advice. Talk to a qualified healthcare professional for medical questions.
Wellness only
LunaFit is for fitness and nutrition tracking, not a medical device, and does not provide medical advice. Every body is different. If you have a health condition or questions about your cycle, consult a healthcare professional.
