A "fingerprint" is not one single value — it is dozens of small, mostly harmless-looking facts about your browser (screen size, installed fonts, how your GPU draws a curve, timezone, CPU core count…) combined together. None of them alone identifies you, but a tracker who sees enough of them at once can often single you out among millions of visitors without ever setting a cookie, and the combination stays stable across sessions and even across "private" windows. Each fact contributes some entropy — bits of information that narrow down who you could be. The estimate below adds up a rough entropy contribution per signal on this page. It is a simplified, illustrative estimate (not a rigorous measurement against real-world population data like EFF's Panopticlick or amiunique.org use) — but it is directionally correct: the higher the number, the more this combination stands out.
