Privacy

The short version: we store a city, a time to the nearest hour, and two optional ticks. Nothing that identifies you.

When you press "I have it"

We save one row with:

• The city you picked from our list (stored as a GeoNames city number). You can't type a free-text place, and we never ask your browser for your location.
• The time, rounded down to the hour, in UTC.
• Two optional yes/no ticks, only if you tick them: "someone else in my family has it" and "it's caught me while driving or riding".

We don't store your name, email, IP address, exact location, device details or anything else. There are no accounts.

Stopping spam

• Your browser remembers you've added a city using local storage (a small note kept on your device, not a cookie, and never sent to us). Clear your browser data and it's gone.
• Rate limiting. To slow down bots, the server turns your IP address into a scrambled code (a salted hash that changes every day) and counts how many submissions that code made in the last hour and day. The raw IP address is never written down. These counters are deleted automatically after about two days, and they're kept separate from the registrations.
• Cloudflare Turnstile (a privacy-friendly check that you're human) may be switched on if bots become a problem. If it is, Cloudflare processes some technical data to run the check, under its own privacy policy. It's currently off.

The map

The map only ever shows a count per city, placed at the city centre. Individual registrations, times and ticks are never shown. The optional ticks are only shown as overall totals.

Cookies and tracking

None. No analytics, no ads, no tracking pixels, no third-party fonts. The map background comes from OpenStreetMap's tile servers, so your browser asks them for map images when you view the map.

Hosting

The site runs on Cloudflare. Like any web host, Cloudflare handles your IP address to deliver the page and protect it from attacks.

Who is responsible

The ACHOO project runs this site and is responsible for the data described here. Questions: hello@achoosyndrome.org (placeholder until the domain is bought).

Getting your entry removed

Because we store nothing that links an entry to you, we can't find "your" row to delete it. That's the trade-off for keeping it anonymous.
