Privacy Policy

What We Collect

When you connect your Sleeper account, we access:

• Your Sleeper username and user ID
• Your league IDs, rosters, and league settings
• Transaction history (trades, waivers, drops) within your leagues
• Draft results and pick ownership

We do not collect your Sleeper password. Authentication is handled entirely through Sleeper's public API using your username.

How We Use It

Your data is used exclusively to power GWTTKB features: power rankings, trade analysis, scouting reports, and AI coaching. We process your league data in real-time and do not store roster or transaction data permanently on our servers.

What We Don't Do

• We do not sell your data to third parties. Ever.
• We do not share your data with advertisers.
• We do not store your Sleeper credentials.
• We do not modify your Sleeper leagues, rosters, or transactions.
• We do not track your browsing activity outside of gwttkb.com.

Cookies & Local Storage

We use browser localStorage to remember your league ID and username between sessions so you don't have to re-enter them. No third-party tracking cookies are used. GWTTKB products are ad-free.

AI (The Coach)

When you use The Coach, your league data (rosters, trades, picks) is sent to our AI provider to generate responses. This data is processed in real-time and is not stored or used for training. Each conversation is independent.

Data Retention

We do not maintain a persistent database of your league data. When you close the browser tab, your session data is cleared. Cached data in localStorage can be cleared at any time through your browser settings.
