Privacy Policy for Underdog Overlay

Introduction

Welcome to the Flock Fantasy Underdog Overlay extension. This privacy policy explains how we collect, use, and protect your information when you use our extension.

Data We Collect

• Authentication Token & User ID — Stored locally on your device to authenticate API requests to Flock Fantasy servers.
• Draft Page URL — Read in memory to detect when you are on an Underdog Fantasy draft page. Never transmitted or persisted.
• Draft Page Content — Player names, positions, teams, and pick data are read from the page to display overlay features. Held in memory only for the duration of the draft session.
• WebSocket Messages — Live pick events on Underdog Fantasy are intercepted to track draft progress in real time. Held in memory only.
• Overlay Preferences — Your display settings (toggles for deltas, stacks, ownership) are stored locally on your device.

Data We Do NOT Collect

• Names, email addresses, or other personally identifiable information
• Browsing history outside of Underdog Fantasy draft pages
• Financial or payment information
• Health information, location data, or keystroke logging

How We Use the Data

• Draft Intelligence — All collected data is used exclusively to power overlay features including roster construction recommendations, stack highlights, ADP movement deltas, and portfolio ownership percentages.
• No Data Sharing — We do not sell, rent, trade, or transfer any user data to third parties. Data is transmitted only between the extension and Flock Fantasy servers.
• Security Measures — All API communication uses HTTPS encryption. Authentication tokens are stored locally using Chrome's storage API.

Data Storage & Retention

Authentication tokens and preferences are stored locally on your device using Chrome's storage API. Draft session data is held in memory and discarded when you close or navigate away from the draft page. Local storage persists until you uninstall the extension or clear extension data.

• Click the extension icon and log out to stop all API communication.
