FAQ

Is my payment data safe?
Yes. All data is encrypted with AES-256 and stored exclusively in your browser's local storage. It never leaves your device or touches our servers.
Which browsers are supported?
FormFill Pro uses Manifest V3 architecture and works on Google Chrome and Microsoft Edge. Firefox support is on the roadmap.
How does the form detection work?
A lightweight content script scans page DOM for common checkout field patterns (name, address, card number, etc.) and fills them using your saved profiles.
