Information we collect
We may collect account identifiers, display names, worksheet settings, generated worksheets, practice results, credit records, and basic technical data needed to run the service.
How we use information
We use this information to create worksheets, run online practice, manage credit balances, show account history, protect the service, and fix reliability issues.
Authentication and account data
Authentication is handled through Clerk. MathDrillPro stores the account reference needed to connect a signed-in user with worksheets, credits, practice sessions, and review items.
Credits and transaction records
Credit balances, credit use, recharge orders, and payment notification records may be stored so you can review account activity and so the service can avoid duplicate charges. Creem handles payment checkout when top-ups are enabled.
Cookies and local storage
The app may use cookies, local storage, or similar browser storage for authentication state, session continuity, and product preferences.
Data retention
We keep records while they are needed to provide the service, support account history, meet operational needs, or handle disputes.
