Or enter manually:
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.
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.
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.
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.
• 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.
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 an aggregation-only 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.
Why 11 people?The k≥11 threshold means no health pattern is ever displayed unless at least 11 separate people contributed to that specific metric in the same 3-digit ZIP area. This exceeds the European Medicines Agency standard (k≥5) and Health Canada standard (k≥5). With a 3-digit ZIP prefix covering 20,000+ people, and at least 11 contributors required, re-identification is statistically impossible.
Data lifecycle:Your contribution is stored as a single row: year-month (not exact date), 3-digit ZIP, age range, gender, and readings. A random ID prevents duplicate counting. The row cannot be traced to you. Raw data is accessible only to the community Data Steward. The public display shows only aggregates that meet the 11-person threshold. If the community Sheet is ever deleted, all data is gone permanently — there are no backups held by anyone else.
This is completely optional. Your vitals check works the same either way.
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.
