How the score works

Each reading is your real value (shown ), a value everyone on your browser shares (blended ), or nothing (refused ). Only shown readings help a tracker.

The score is the share of what this tool checks that stays hidden, weighted by how identifying each reading is. It does not estimate how rare you are. A strong reading still shown is named next to the grade.

A high score means the fingerprint is hidden, not that you are untrackable: your IP and TLS are sent before any script. Blended is credited only for values a browser is documented to share. Method and working in METHODOLOGY.md.
