Does this store my IP address?▾
Never. Your IP is hashed with a daily-rotating salt before storage. We cannot reverse it.
How long does the test take?▾
About 5–10 seconds. All checks run directly in your browser.
What is a supercookie / UIDH?▾
Verizon and some ISPs inject a unique identifier into HTTP requests that advertisers can read — even in private browsing mode.
Will a VPN fix my score?▾
Yes — a VPN encrypts all traffic before it reaches your ISP, preventing header injection and DNS surveillance.
