Fingerprinting explained
Fingerprinting fills the gap when users clear cookies but marketers still want persistence. Understanding exposed signals is the first step toward meaningful privacy choices.
Common signals
User agent, language, timezone offset, screen resolution, color depth, installed plugins (where exposed), and WebGL renderer strings each narrow the candidate pool.
Not a security scanner
High entropy is not malware. Developers use the same signals for fraud scoring and bot detection—context determines whether persistence helps or harms you.
Regulatory lens
GDPR and ePrivacy treat persistent identifiers as personal data in many cases. Privacy policies should disclose fingerprinting if your site employs it beyond this demo.
