Learning and self-check methodology

House of Kacinari Learn is for learning, practice, and immediate self-checking of understanding. It does not run formal examinations, issue certificates, or create professional qualifications.

Lessons and anonymous practice

A lesson provides structured context. Practice selects questions from the private versioned source, returns a score and explanation immediately after submission, and does not require an account, name, or public profile.

Boundaries

A self-check result does not by itself measure instrument handling, independent stone identification, practical grading, valuation, workshop or laboratory competence, or overall professional ability.

Integrity and privacy

Answer keys remain private on the server side. The practice token is signed and time-limited, and responses are scored only for questions included in that token. Results and attempt history are not stored as learner records, and learner progress is not stored in localStorage, cookies, or IndexedDB.
