How Your Progress is Stored Locally
Dutch Driving Theory Hub requires no account creation, no password, and no personal email address. All study progress records, reading dwell time telemetry, completed mock exams, and quiz scores reside exclusively inside your browser via standard HTML5 localStorage and sessionStorage APIs. No user data is ever transmitted to remote databases.
