Educational purpose
The tests, scores and guides on this site exist to explain how browser fingerprinting, network attribution and bot detection work. They are simplified, transparent models — not the proprietary systems used by large platforms.
No professional advice
Nothing here is legal, security, compliance or financial advice. If you need a formal privacy or security assessment, consult a qualified professional.
Accuracy of results
Browser APIs vary between vendors, versions and privacy settings. Values may be spoofed, randomised or unavailable, so a “low risk” result does not mean you are anonymous and a “high risk” result does not mean you did anything wrong.
No affiliation
This site is independent. It is not affiliated with, endorsed by, or sponsored by Microsoft, Google, Cloudflare, Stripe, or any browser vendor. Product names are used only to describe publicly documented behaviour.
External links and ads
We link to third-party resources and display advertising. We are not responsible for the content, accuracy or practices of external sites.
