Privacy Policy

What We Collect

Dynasty Helper collects the minimum data needed to operate the service:

• Sleeper account info — If subscribing to a Pro plan, your Sleeper User ID is stored alongside your Stripe subscription to link the two.
• Subscription data — if you subscribe to Pro, Stripe stores your payment information. We only store your Sleeper user ID as metadata on your Stripe customer record. We never see or store your credit card number.
• Usage data — anonymous page views and performance metrics via Vercel Analytics. No personally identifiable information is collected by analytics.
• Local storage — we store preferences and Sleeper authentication codes in your browser's local storage. This data is not sent to our servers.

How We Use Your Data

• To display your Sleeper leagues, rosters, and matchups
• To execute trades, lineup changes, and waiver claims on your behalf via the Sleeper API
• To manage your Pro subscription via Stripe
• To improve the service using anonymous analytics

Third-Party Services

• Sleeper — we interact with Sleeper's API to read and write league data using your authentication token.
• Stripe — handles all payment processing. See Stripe's Privacy Policy.
• Vercel — hosts the application and provides analytics. See Vercel's Privacy Policy.

Data Retention

We do not maintain a database of user data. Your Sleeper data is fetched in real time or stored in your browser's local storage, and never sent to our servers. Stripe customer records persist as long as your subscription is active. You can request deletion by contacting us.

Your Rights

You can clear all locally stored data by clearing your browser's local storage. To delete your Stripe customer record or request any other data removal, contact us at support@dynastyhelper.com.

Changes

We may update this policy from time to time. Changes will be posted on this page with an updated date.
