HYMN uses essential cookies or equivalent browser storage to maintain authenticated sessions, protect role-based routes, preserve security state, remember interface preferences, and support checkout or onboarding continuity.

Limited diagnostic or usage information may be processed to identify failures and improve workflows. HYMN does not describe essential session storage as optional advertising tracking.

Browser controls can remove or block cookies, but doing so can sign you out, reset preferences, interrupt payment return flows, or prevent protected dashboards from operating correctly.
