Your connected MCP agent can read your quiz preferences, quizzes and performance and publish question packs after you approve its access. It cannot submit answers for you. The agent service you choose processes data under its own terms.
Account data is stored in Cloudflare D1. App credentials are held in iOS Keychain; the server stores only hashes of app and MCP credentials. The app caches quiz data on your device. There is no advertising or cross-app tracking.
Disconnect agents in Settings. Delete your account and its associated quiz data in the app after confirming with Apple. Local reminders are optional.
