Health Disclaimer

Last updated: August 2026

Informational purposes only

The Health Box on Toolsda (BMI Calculator, BP Checker, Fever Checker, and related tools) exists to help you understand publicly published wellness reference ranges. Nothing on these pages is medical advice, a diagnosis, or a treatment plan, and none of these tools are a substitute for professional judgment.

Not a substitute for a doctor

Always consult a qualified healthcare professional about any health question or concern — especially before making decisions based on a reading from one of these calculators. If you believe you're experiencing a medical emergency, contact your local emergency services immediately; don't wait on a tool result.

Where the ranges come from

Every range shown in the Health Box is sourced from publicly published guidelines from recognized health bodies, and cited on each tool. The single source of truth for these ranges lives in our codebase (lib/health-standards.ts) so they can be reviewed and updated as guidelines change:

Guidelines are periodically revised by these organizations. We aim to keep our ranges current, but always check the linked source or a healthcare professional for the most up-to-date clinical guidance.

Your data stays on your device

Health Box tools run entirely in your browser. Nothing you enter — height, weight, blood pressure, temperature, or any other reading — is sent to a server, stored in a database, or shared with any third party. See our Privacy Policy for the full picture.

No liability

Toolsda and its creators are not liable for decisions made based on the output of these tools. Use them as a starting point for a conversation with a healthcare professional, not as a final answer.
