Privacy Policy
Ultimate Fantasy Dashboard Chrome Extension
This privacy policy explains how the Ultimate Fantasy Dashboard Chrome Extension ("the Extension") collects, uses, and protects your information.
Summary: We only read two ESPN cookies and only send them to ultimatefantasydashboard.com. We do not collect, store, or share any other data.
What Data We Collect
The Extension collects only two pieces of information:
- espn_s2 - An ESPN authentication cookie
- SWID - An ESPN user identifier cookie
These cookies are required by ESPN's Fantasy API to access your private league data. Without them, ESPN returns incomplete data for category leagues.
How We Use Your Data
The collected ESPN cookies are used solely for one purpose:
- To authenticate API requests to ESPN's Fantasy servers on your behalf
- This allows Ultimate Fantasy Dashboard to display your league standings, matchups, and statistics
Where Your Data Goes
Your ESPN credentials are:
- Stored locally in your browser's localStorage on ultimatefantasydashboard.com
- Sent only to ESPN's official API servers (via our secure proxy) to fetch your league data
- Never sent to any third parties
- Never stored on our servers
What We Do NOT Collect
The Extension does NOT collect:
- Your ESPN username or password
- Your browsing history
- Data from any websites other than ESPN
- Personal information such as your name, email, or location
- Any cookies other than espn_s2 and SWID
Data Security
Your ESPN credentials are:
- Transmitted securely using HTTPS encryption
- Stored only in your local browser storage
- Never logged or recorded on any server
- Automatically cleared if you log out of ESPN
Your Rights
You can at any time:
- Stop syncing by simply not clicking the sync button
- Remove the extension from Chrome to stop all data collection
- Clear your data by clearing localStorage on ultimatefantasydashboard.com
- Revoke access by logging out of ESPN (which invalidates the cookies)
Third-Party Services
The Extension interacts with:
- ESPN Fantasy API - To fetch your league data using your credentials
- Ultimate Fantasy Dashboard (ultimatefantasydashboard.com) - To display your league information
We do not share your data with any other third parties, advertisers, or analytics services.
Changes to This Policy
If we make changes to this privacy policy, we will update the "Last Updated" date below. Continued use of the Extension after changes constitutes acceptance of the updated policy.
