FAQ
Quick answers. No walls of text.
Does this identify me personally?
No. It shows the fingerprint surface your browser exposes, not your real-world identity.
Why does the fingerprint change?
Browser version, extensions, settings, hardware, graphics, language, and display changes can all affect it.
Is a high surface always bad?
Not automatically, but more stable exposed signals generally give trackers and anti-fraud systems more material to work with.
