About

SickMap

A live, anonymous map of symptoms and remedies — built to help communities spot outbreaks early, protect the people most at risk, and talk openly.

What SickMap is for

Spot outbreaks early

See in real time what's going around in your neighbourhood, workplace, or city — before the news picks it up. When a cluster of coughs or GI symptoms starts trending on your block, you get to know first.

Protect people at risk

If you're immunocompromised, pregnant, caring for someone vulnerable, or just planning around a big event, SickMap shows where illness is concentrated so you can steer around it. Less guesswork, fewer surprises.

Find remedies that actually worked

Every cluster keeps a community-driven list of what helped — the tea, the OTC, the rest schedule. Real people, same symptoms, not an ad-driven search result. Upvote what worked, flag what didn’t.

You're not alone in being sick

Symptoms — physical or mental — are isolating. Seeing that dozens of others around you are fighting the same cold, migraine, or anxiety spike reduces the “is it just me?” panic and opens up space to talk about it openly.

Prevention through shared data

Every anonymous report adds to a public-health signal that has historically only lived inside hospital systems and research institutions. Aggregated properly, it’s one of the cheapest ways to flag emerging illness patterns and prevent spread.

How your data is protected

We share insights, not identities

The whole point of SickMap is to make population-level patterns visible without making any individual identifiable. That’s baked into the database, not added on afterwards.

Your location is fuzzed

Exact GPS never leaves your device. Before any report is saved, we randomize the coordinates by ~300 metres and snap them to a neighbourhood-level hex grid (H3 resolution 8). Nobody — including us — can trace a pin back to your door.

Your identity is not attached

Usernames and emails are for account management only. When other users see a cluster or a cluster’s reports, they see anonymized cards — no username, no avatar, no handle.

We publish insights, not data

What's shared publicly is aggregated: “6 people reporting wheezing near here”, “average severity 3.2”, “top remedies were rest and hydration”. The individual rows behind those numbers stay private, protected by row-level security in our database.

k-anonymity on every cluster

A cluster isn't surfaced until at least three distinct reporters show up in the same hex. If you're the only one reporting in your area, nothing about you appears on anyone else’s map.

You are in control

Under MHMDA (Washington), CCPA (California) and GDPR (EU) you can export everything we hold about you or permanently delete your account and every associated report. Both are self-serve from Profile.

Not medical advice

SickMap shows what people near you are reporting. It is not a diagnosis, a substitute for a clinician, or an emergency service. If something feels serious, call your local emergency number or seek professional care.
