+- **D33 The body's figures in a sealed, synced profile** (recommended, the developer's;
+  over this phone alone, and over keeping them nowhere): one synced model, `profile`,

+  first-time use needs (sex as Polar's formulas take it, birth date, height, weight,
+  resting and highest heart rate, VO2max, training background, typical day, sleep goal),
