FillFast Privacy Policy

Last updated: April 4, 2026

Overview

FillFast is a Chrome browser extension that saves web form field values locally on your device and replays them on demand. This policy explains exactly what data is handled and how.

Data We Collect

FillFast stores the following data locally on your device using chrome.storage.local:

• The URL of pages where you choose to save a form
• The values you entered in eligible form fields (text inputs, dropdowns, checkboxes, etc.)
• The timestamp of when you saved a profile

Data We Do Not Collect

• Passwords — password fields are never read or stored
• Hidden fields — hidden, file, and system inputs are always skipped
• Browsing history — the extension only acts when you explicitly click Save or Fill
• Personal identity data — no names, emails, or any content is collected by the developer

Data Transmission

FillFast does not transmit any data to any server. All saved form data remains entirely within your browser's local storage and is never sent over the network. The extension makes no network requests of any kind.

Data Storage and Deletion

Data is stored in chrome.storage.local on your device. You can delete saved profiles at any time by clicking the × button next to any profile in the FillFast popup. Uninstalling the extension removes all stored data.

Permissions Explained

• activeTab — used to identify which page you are currently on, so the correct saved profile can be loaded or saved.
• storage — used to persist your saved form profiles locally in your browser.
• Content script on all URLs — the extension injects a script to read and fill form fields on whichever page you are visiting. This script only runs when you click Save or Fill; it does not monitor or record your activity passively.

Third Parties

FillFast does not share data with any third parties. There are no analytics, tracking pixels, crash reporters, or external dependencies of any kind.

Changes to This Policy

If this policy changes, the updated version will be published at this URL with a revised "Last updated" date.
