Encrypted intake forms.

Your server never sees the data.

Every field is encrypted in your visitor's browser before it leaves their device. You are the only person who can read your submissions.

Zero plaintext on server RSA-2048 + AES-256-GCM Private key stays in your browser

🔒

Zero-knowledge architecture

Your data is encrypted before it leaves the visitor's browser. No one — not your host, not us — can read it.

🔑

Private key stays with you

Your decryption key is generated in your browser and stored there. It is never transmitted or stored on a server.

🛡

End-to-end encrypted

From the moment a visitor types into your form to the moment you decrypt it in your browser — the data is always encrypted.

How it works

✍

Visitor fills out your form

Nothing is sent to your server yet.

🔒

Data is encrypted in their browser

Each field is scrambled with AES-256 before the visitor hits Submit.

🛡

Your server receives only ciphertext

Encrypted data arrives at your server. It is unreadable without your private key.

🔑

Only you can decrypt it

Your private key lives in your browser. Nobody else has it.

Everything you need in a secure WordPress form builder.

🔧

Drag-and-drop form builder

20+ field types including signature, file upload, repeater, and multi-step forms.

⚙

Conditional logic

Show or hide fields based on visitor responses. No coding required.

🔒

Zero-knowledge encryption

We cannot read your submissions. Your host cannot. No one can — except you.

💾

Encrypted key backup

Passphrase-protected key backup so you never lose access to your submissions.

🚫

No reCAPTCHA

Honeypot and math CAPTCHA built in. No Google surveillance on your forms.

📄

Export submissions decrypted entirely in your browser. Nothing sent to a server during export.
