It works wherever your visitors are.
Nothing on the widget path touches a Google domain, so the challenge behaves the same on privacy browsers, hardened networks and in regions where those services are unreachable.
How it works
No third-party request to fail
A captcha that depends on a blocked domain does not degrade - it stops the form working at all. Ours has nothing external to block.
Privacy browsers are ordinary visitors
Hardened browsers are not penalised for being hardened. They are scored on the same signals as everyone else.
No country-level gating
We do not block regions or carriers. A mobile NAT can sit in front of thousands of real subscribers, so difficulty is sized per request instead.
What that means concretely
Each of these is a statement about how the product behaves, not a description of how we feel about it.
