Privacy
Dynasty Toolbox uses account information to let you sign in and save your leagues.
Account information
We store your email address, account identifiers, and the Sleeper league IDs and team preferences you choose to save. Supabase handles password authentication and stores a password hash. Your password is sent securely when you sign in or change it; it is not displayed in your account or stored in browser storage.
Services we use
Vercel hosts the website and account service, Supabase stores accounts and saved leagues, and Resend delivers verification and password-reset emails. These services process information needed to provide those features, including technical and security logs. Sleeper provides league and roster information when you enter or load a league ID.
Some public tool pages use Google Analytics to measure website use and Google Fonts to display fonts. The account page does not load Google Analytics. Browser requests can share technical information such as your IP address with the services involved.
Browser storage
Account sessions use cookies that website JavaScript cannot read. Public tools also cache rankings and may remember recently used league IDs when you are signed out. When you are signed in, My Leagues uses your saved account entries instead of that recent-league history.
Your choices
You can remove a saved league in My Leagues and sign out on your account page. Removing a league here does not change it in Sleeper. Account information is retained while your account exists; provider security logs and backup copies can have separate retention periods.
To request account deletion or ask about your information, contact dynastytoolbox@gmail.com. Do not send passwords or verification codes.
