What this collects
Everything happens in your browser. Footprintz has no account, no cookies and no analytics, and it doesn't save or send what it reads. When you close the tab, it's gone.
When you open the page
Your browser downloads the page's own files. The site only checks one thing at this point: your reduced-motion setting, so the footprints at the top stay still if you've asked for less animation.
When you click Generate
Nothing else is read until you click. Then the page reads these from your browser, and uses them to grow your flower and fill in the report:
- Your public IPv4 and IPv6 addresses, which this site echoes back to your browser so the report can show them (they are never stored, and don't affect your flower)
- Operating system and browser name
- Timezone
- Date and number formats (12- or 24-hour clock, decimal separator)
- Languages
- The names of the text-to-speech voices installed on your system (nothing is spoken)
- Screen size and pixel ratio
- Screen colour depth, colour range and HDR support
- What kinds of pointer your browser reports (mouse, trackpad, touch) and how many touch points
- CPU core count
- Graphics hardware name
- Dark mode and reduced-motion settings
- Global Privacy Control and Do Not Track settings
- Whether an ad blocker stopped a test file
- A canvas fingerprint: a hash of a small test drawing, which is skipped if your browser would ask for permission
- An audio fingerprint: a hash of a short tone processed silently in your browser, never played or recorded
- Your local network address from WebRTC, if your browser reveals it
Your flower is also shaped by a random number made in your browser for each growth, so no two are the same.
What leaves your browser
Nothing you see in the report. The ad-blocker check asks this site for two empty files, and the IP lines ask this site for your address twice, once at footprintz.fyi and once at ipv4.footprintz.fyi, which only answers over IPv4; none of these requests carry any results. The WebRTC check uses no outside server, and the page loads nothing from any other site.
Hosting
Like every website, this one can't reach you without your IP address. The site is hosted on Amazon CloudFront, which handles that address to deliver pages and to limit abusive traffic. The site has access logging turned off, so it keeps no record of your visit or your IP address. The IP address lines come from a small function at the edge that reads your address from the connection and sends it straight back; it is not written anywhere.
Changes
This page describes what the site does today, and it will be updated before that changes.
