What we collect
BNB Dojo collects the information you provide when signing in with Google: your display name, email address, and profile photo. We store your learning progress, XP, belt rank, and daily check-in streak in our database.
How we use your data
Your data is used solely to provide the BNB Dojo experience: displaying your progress, powering the leaderboard, and enabling the belt progression system. We do not sell your data to third parties.
Local storage
BNB Dojo stores your session data and preferences (language, rank) in your browser's local storage. This data never leaves your device except as part of normal API communication with our servers.
Authentication
Authentication is handled by Supabase using Google OAuth. We never see or store your Google password. Your Supabase session token is stored in memory only and expires after the session ends.
Public profile
Your username, belt, country flag, and XP are visible to other BNB Dojo users on the leaderboard and public profile pages. You can update your display name and country in your profile settings at any time.
Data retention
Your account data is retained as long as your account is active. You can request account deletion by contacting us at the email below. Deleted accounts are removed from active leaderboards within 30 days.
