100% Client-Side Persistence
Privacy & Data Architecture
Designed guest-first with zero tracking and browser-only persistence.
No Server Database
Your answers, scores, job descriptions, and past attempts are stored locally on your device in your browser's IndexedDB. They are never saved to a remote server database.
Ephemeral AI Processing
Questions and evaluation rubrics are processed ephemerally on the server solely for generation and structured scoring. Prompts and answers are not logged or stored permanently on the server.
Zero Answer Leakage
Correct answer keys and grading criteria are sealed with server-side cryptography during active exams, preventing any leakage via browser inspect tools until after submission.
