This is health data. Turning it on asks for a separate, specific, withdrawable consent — never bundled into signing up.

Worth knowing: England only — the Health Survey for England does not cover Scotland, Wales or Northern Ireland. Percentiles are derived directly from HSE's published BMI category shares (the proportion of adults below each clinical boundary: 18.5, 25, 30 and 40), because HSE publishes category shares and a mean, not percentiles. Placements outside that range are clamped to the nearest boundary.
