Privacy Policy
Last updated: March 1, 2026
Data We Collect
When you sign in with Google, we receive your name, email address, and Google account ID via Firebase Authentication. This is used solely to identify your account.
The extension captures your fantasy draft picks from Underdog Fantasy while you draft. This data is stored exclusively on your local device using Chrome's built-in storage (chrome.storage.local) and is never transmitted to our servers.
How We Use Your Data
Your Google account information is used to authenticate you and associate your account with the extension.
Your draft data powers the extension's analytics features — exposure tracking, ADP value, and positional construction. All processing happens locally on your device.
We do not use your data for advertising, profiling, or any purpose beyond operating the extension.
Data Storage
Draft picks and related fantasy data are stored locally on your device in Chrome's extension storage. This data does not leave your device.
Your Google account information (name, email address, Google ID) is stored by Firebase Authentication, a service provided by Google LLC, and is subject to Google's Privacy Policy.
Data Sharing
We do not sell, rent, or share your personal information with third parties. Your draft data is never transmitted to our servers or any third party.
Data Deletion
To delete your local draft data, uninstall the extension from Chrome. All locally stored data is removed automatically.
To delete your account and associated authentication data, email support@bestballexposuretracker.com. We will process your request within 30 days.
Third-Party Services
The extension operates on Underdog Fantasy (underdogfantasy.com). We are not affiliated with or endorsed by Underdog Fantasy.
Authentication is provided by Firebase, a service of Google LLC.
