Connection
Cloudflare incoming request metadata supplies the observed IP and any available approximate country, region, city and network organization. A local preview cannot reproduce that production observation.
Passwords
The generator uses WebCrypto random values. The local strength estimator is zxcvbn-ts. English passphrases use EFF's 7,776-word long list, attributed under CC BY 4.0. The optional breach check contacts only the official Have I Been Pwned Pwned Passwords range API after an explicit click.
Domains and optional tests
After an explicit click, RDAP uses the IANA bootstrap and a registry server, DNS uses Cloudflare DNS over HTTPS, IPv6 uses the IPv6-only ipify endpoint, and WebRTC uses Cloudflare STUN. These observations do not prove domain purchase availability, VPN protection or anonymity.
