Privacy explanation

The BMI and TDEE widgets run calculations in the browser and do not require account sign-in. They are screening and planning tools, not diagnosis, medical advice, or individualized nutrition care.

Example use cases

• Embed TDEE beside a calorie-deficit, maintenance-calorie, or nutrition-planning guide.
• Give readers a quick calculator while linking to methodology and limitations for health-sensitive topics.

Methodology and limitations

• BMI uses weight divided by height squared and displays adult category context with limitations.
• TDEE estimates BMR and daily energy needs using activity inputs and visible assumptions.
• Health results are informational estimates and should be paired with source notes and professional-care cautions.
