Information we process
We process account information, saved study activity, exam attempts and results, and limited technical analytics needed to operate and improve Learn HSK. Payment details are processed by Lemon Squeezy; Learn HSK stores order and entitlement identifiers rather than complete card details.
How information is used
Information is used to authenticate users, save progress, provide purchased access, prevent abuse, answer support requests, and understand aggregate product performance.
Service providers
Learn HSK uses Supabase for authentication and data, Vercel for hosting and privacy-safe product analytics, Supabase Storage for media, and Lemon Squeezy for checkout and payment administration.
