❓ Frequently asked questions
How is the score calculated?▼
Many browser traits (canvas, fonts, hardware, settings) are used to estimate entropy and thus your browser's uniqueness — all locally.
Is my data transmitted?▼
No. The entire analysis runs in your browser. No fingerprint data is sent to a server.
What does a high score mean?▼
A high score means your browser is very unique and therefore recognizable without cookies. Lower is better for your privacy.
Is the share card safe?▼
Yes. It's generated locally from your result (as an image) and contains only the score — no identifying raw data.
