1. Overview
This Privacy Policy explains how Flash Fill ("we", "us", or "our") collects, uses, and handles your data when you use our browser extension. We are committed to protecting your privacy and ensuring that all data processing is transparent and secure.
Flash Fill is an open-source productivity tool designed to automate form filling through user-defined rules and regex patterns. Privacy is our priority: all data management happens locally on your machine.
2. Data Collection and Usage
Flash Fill handles the following types of user-provided information:
- Autofill Rules and Patterns: When you create a "Fixed ID" or "Regex" rule, the extension stores the keywords, patterns, and values you provide. This data is used exclusively to identify and fill fields on websites you visit when you trigger the extension.
- Temporary Page Content: To identify form fields, the extension temporarily reads the structure (DOM) of the active tab. This information is processed in real-time and is never stored, logged, or transmitted.
3. Data Storage
Local Storage only: All rules and values are stored using the chrome.storage.local API. This data remains on your local device and is tied to your browser profile.
No Cloud Sync: We do not use cloud synchronization services. Your data does not leave your computer.
Security Warning: Please note that data in local storage is stored in a format that could be accessible to other software with access to your system. We strongly recommend not storing sensitive information like passwords, financial data, or private keys in Flash Fill.
4. Data Sharing and Third Parties
Zero Sharing: Flash Fill does not share your data with any third parties, including the developers, external companies, or analytics services.
No External Servers: The extension does not communicate with any external servers. There are no tracking scripts, analytics, or background telemetry.
5. Permissions Disclosure
Flash Fill requires the following permissions to function:
