Community illness tracker · free

See what’s going around. Keep your family’s details at home.

Made by a small independent developer. Not Big Tech, and never will be.

BugNet is a health journal for your household. Log who’s sick, their symptoms and what helped. Your check-ins, joined with your neighbors’, show what’s going around your area this week, and what other families say worked.

Android first, straight from this website. iPhone later. The practice run needs no sign-up: a pretend family, nothing saved.

What it does

A journal for the whole family

Symptoms, temperatures, sleep, food, remedies and how they went, per person. One tap for “all well this week”, because healthy weeks count too.

What’s going around

See this week’s stomach bugs, flu-like illness and colds in your 3-digit ZIP area, compared with the usual. Area alerts when something is clearly rising.

What other families say helped

Shared experiences, with the number of families behind every figure. It records and informs; it never diagnoses or prescribes.

How privacy works

Only a 3-digit ZIP. You tell BugNet the first three digits of your ZIP code, never the full one, and never your GPS location.
Names stay on your phone. The server sees each family member as an age band and sex, nothing more. Tap a name in a note and it is replaced by a token before anything is sent.
Photos stay on your phone. They are never uploaded.
Email is optional. Add one only if you want to restore your account on a new phone.
Messages are end-to-end encrypted. Not even we can read them.
No ad trackers, no data brokers. No tracking ad SDKs, in the app or on this site.

The details are in the privacy policy (draft).

Try it: the first 3 digits of a ZIP

Demo with Nebraska, South Dakota and Minnesota (2020 Census ZIP areas). It runs in your browser; nothing you type is sent anywhere.
