Check Your Vitals

Enter your numbers. Get a plain-language explanation of what they mean and what to do. Nothing is saved. Nothing is sent. When you close this page, your data disappears.
⚠️ This is not medical advice. This tool provides educational information about vital sign ranges. It does not diagnose conditions, replace a doctor's evaluation, or account for your personal medical history. If you are experiencing a medical emergency, call 911 immediately. If you have concerns about any reading, contact your doctor or visit a Federally Qualified Health Center.
🔒 Zero Data Storage
Your vitals exist only in your browser while this page is open. Nothing is saved to any server, database, cookie, or local storage. When you close this tab, your numbers are gone forever. Nobody — not this platform, not your employer, not your insurance company — can see what you entered.

bpm

🩺 Blood Pressure

Enter your systolic (top number) and diastolic (bottom number). If you don't have a cuff, any pharmacy with a free kiosk will measure it — CVS, Walgreens, Walmart.

/ mmHg

🩸 Blood Glucose

Enter your fasting blood glucose (first thing in the morning, before eating). If you've already eaten, this reading will be higher than your true fasting level.

mg/dL

🌡️ Temperature

°F

⚖️ BMI Estimate

BMI is a rough screening tool, not a diagnosis. It doesn't account for muscle mass, bone density, or body composition. Athletes and people with high muscle mass often have elevated BMI without health risk.

🫀 Community Health Pulse

Want to help your community? You can contribute your vitals anonymously. Only your 3-digit ZIP prefix, age range, and gender are sent — never your name, email, exact age, or exact ZIP. Your community sees patterns, not people.

What we collect:

• 3-digit ZIP prefix (e.g., 606 — never your full ZIP code)
• Age range (e.g., 30-39 — never your exact age)
• Gender (optional)
• The vital sign readings you choose to share
• Nothing else. No name. No email. No IP address. No timestamp precise enough to identify you.

What we never collect:

Your name, email, phone number, address, insurance information, immigration status, employer, or any information that could identify you personally. This data cannot be sold, shared with insurers, or used for any purpose other than showing your community its own health patterns.

How it's protected:

Data is stored in a community-owned Google Sheet under CARE/OCAP governance principles. Patterns are only displayed when 11 or more people in the same group have contributed — below that threshold, the data exists but is never shown. You can never be identified from the aggregate display.

This is completely optional. Your vitals check works the same either way.

When you close this tab, every number you entered is gone. Nothing was saved. Nothing was sent. This page has no memory.

Vital sign ranges based on AHA, ADA, and CDC guidelines. This tool is educational. It is not a medical device. In an emergency, call 911.
