Privacy Policy
No accounts. No backend. Your data stays on your device.
1. What we store
All inputs (profile, macro choice, generated meals, exercise, history) are saved to
localStorage on this device under the key
energy-balance:v1:state. Nothing is sent to a server.
2. Cross-device sync (optional)
If you sign in via the platform's shared auth (AuthSync), the same state blob is pushed/pulled to your account so you can resume on another device. The blob is opaque to the platform and is only readable by you.
3. Nutrition & exercise data sources
Nutrient values are pre-computed from the Korean FDA (식약처) Food Nutrient DB (100g basis). MET values are from the ACSM Compendium of Physical Activities (2011). All values are estimates — individual variation ±15-20%.
4. Medical disclaimer
This tool is for general guidance only. It is not medical advice and must not be used for medical decisions. Consult a licensed clinician for personalized guidance.
5. Reset / export
Use the Data menu (⚂ in the top-right) to export your data as JSON, import on another device, or reset everything.
Anonymous visit counting via the platform's shared beacon may be active. No personal data is collected.
