Security Toolkit

Small, privacy-first security tools that run entirely in your browser. No accounts, no tracking, no data stored anywhere.

Your data never leaves your device

Password Checker

See how strong a password really is, how long it would take to crack, and whether it has leaked in a data breach — without ever sending it anywhere.

Paste the source of a suspicious email and see where it really came from, whether it passed SPF, DKIM and DMARC, and which warning signs it shows.

See everything a website learns about you the moment you open it — and how unique your browser fingerprint is, even without cookies.
