The check only reads values that every website can query without asking. It all happens in your browser; only the IP address is returned once by this server. Nothing is stored. The score is a rough estimate of how easily your device can be recognised.

How to reveal less
- Use Firefox or Brave with fingerprint protection switched on.
- Use a VPN if your IP address should not match you.
- Install a tracker and script blocker (e.g. uBlock Origin).
- Avoid rare fonts, extensions and exotic settings — the more ordinary, the more anonymous.
