What we store
Account profile data, submissions, progress state, query-run metadata, session/security events, and billing state required to operate the platform.
Why we store it
Grading, abuse prevention, session security, product reliability, billing enforcement, and evidence-backed progress reporting.
Retention posture
Retention is controlled by platform cleanup policy for sessions, progress snapshots, and assessment telemetry. The goal is operational necessity, not indefinite accumulation.
User controls
Consent preferences, audit export, portfolio export, session review, and account-level privacy settings are available in the security center.
