FAQ

Is FormKlar free to start?

Yes. Free includes up to 3 forms, embed, inbox, email notifications, export, and API access. Webhooks and removing FormKlar branding / your own logo are on Pro ($9/mo or $90/yr).

Where does my data live?

Form definitions and submissions are stored in Cloudflare D1 (currently ENAM — Eastern North America). Workers run at the edge globally. Export CSV anytime. We don’t sell leads or train models on your data. Details: Privacy and Security pages. No EU-only region lock today.

Can I embed on my own site?

Yes — drop an iframe or HTML snippet. Visitors submit on a page they already recognize as yours.

Do you support company vs individual fields?

Yes. Entity type drives conditional labels (company name vs personal name) in the builder and public form.

How do webhooks work?

On Pro, set a webhook URL on the form. On each submit we POST the JSON payload to your endpoint.

Which languages are supported?

The site ships with G20-focused locales including Simplified/Traditional Chinese, English, Japanese, Korean, French, German, Italian, Portuguese (Brazil), Spanish, Arabic, Russian, Hindi, Turkish, and Indonesian.
