Your visitors' data

Consent first, minimal data, no form data to us.

Nothing is sent before a site administrator gives consent. Only text fields and the e-mail domain are sent; never IP addresses, full e-mail addresses, passwords, payment fields or uploads. Data is processed in the USA by TypeSafe AI, Inc., directly or through your chosen gateway. Thinking42 receives no form data.

FAQ

Do I need anything else?

A Jev API key from TypeSafe direct, Vercel AI Gateway, OpenRouter or your own proxy, plus WordPress 6.6+, Contact Form 7 6.0+ (Flamingo recommended) and PHP 7.4+.

What if the AI service is down?

Formsieve fails open. An outage or a billing problem never blocks a real submission.

What happens when my licence ends?

Filtering keeps working; only updates and support stop.
