Privacy-First Architecture

Security is not
an afterthought

Your profile never touches our servers. Your API key is encrypted locally. Data flows directly from your browser to OpenAI — we are never in the middle.

How we protect your data

🔐

Secure Browser Storage

Your OpenAI API key and profile data are handled automatically by the browser's secure storage mechanism. This ensures that your information remains private and is only accessible locally.

🧠

No Server-Side Storage

FormFill AI has no backend that stores your profile or personal data. Everything lives in your browser's local storage — we have no database of your information.

📡

Direct API Connection

Your data travels directly from your browser to OpenAI's servers. Our servers are never in the middle. No proxy, no storage, no logging.

👁️

Transparent Handling Logic

Our data handling logic is designed for maximum transparency. We provide detailed documentation on exactly how your data is stored and processed, ensuring your privacy is never compromised.

🚫

No Telemetry or Tracking

We collect zero analytics about the forms you fill or the data you enter. Our business model doesn't depend on your behavioral data.

🔑

Dedicated Key Management

Your OpenAI API key is stored exclusively in Chrome's local extension storage. It is never transmitted to our servers or stored in any cloud database we control.

On fill: profile sent directly to OpenAI API from your browser
FormFill AI servers are never in the request path
