Does life.fan write anything to Apple Health?
No. The app reads metrics you permit (weight, body fat, HRV, sleep, steps, workouts) and never writes anything back. Your health data never leaves your device.
How does the fasting clock work?
The clock runs from your last logged food or caloric drink and only resets when you log another. Water, black coffee, and plain tea don't break your fast. Your scheduled eating window is guidance — the clock follows what you actually eat.
Where do the recommendations come from?
Every recommendation in the app carries a citation to peer-reviewed research, visible where the recommendation appears and collected in the in-app Research library. life.fan provides wellness information, not medical advice — always consult your doctor before making changes to your diet, exercise, fasting practice, or supplements.
How do I delete my data?
Delete the app. All plan data is stored on your device, so removing the app removes your data. Supplement label photos sent for research are processed transiently and never stored on our servers.
life.fan is not a medical device and does not provide medical advice, diagnosis, or treatment. Seek the advice of your physician with any questions regarding a medical condition and before making any medical decisions.
