Tanita · Hume · InBody · DEXA · smart-scale export · dietitian plan
1 · We identify the device and read every field
2 · We check the report’s own arithmetic
3 · You confirm each value before it counts
🔒 Consent first, always. Reports are read for your assessment only — never sold, never used for ads. DEXA bone fields are discarded at reading; they’re medical data an app shouldn’t hold.
TRACK B · NO SMART SCALE NEEDED
Tape measurements
Morning · after the toilet · before food · normal exhale · tape flush on skin, never pressing in.
