FoxFill Privacy Policy

Last updated: 7 September 2026

FoxFill is a Chrome browser extension that fills web forms from a profile you manage on your own device. This policy explains what data FoxFill handles and what it does not do.

Single purpose

FoxFill fills web forms from a user-managed profile stored only on the local device. Users scan a page, review matched fields, and choose what to fill.

Data stored on your device

When you enter details in FoxFill (for example name, address, email, phone, ID number, passport number, date of birth, or custom fields), those values are saved in Chrome’s local extension storage (chrome.storage.local) on your computer. You may keep multiple named profiles.

Optionally, you can enable a passphrase so profiles are encrypted at rest on this device (AES-GCM). A recovery email you set is used only for local unlock recovery—not sent to a FoxFill server (FoxFill has no backend).

What we do not collect

Permissions

FoxFill does not use remote code. All scripts ship inside the extension package.

Website interaction

On your command, FoxFill reads form field labels and structure on the current page to match them to your local profile, may highlight fields, and may write values you approved into empty inputs. It does not submit forms automatically.
