  • Session /practice without a Clerk session is still this browser tab only, 5 calculations / 3 clients.
  • Signed-in drafts go to Supabase Sydney (ap-southeast-2). Stored practice calculations are kept 90 days; this host does not run a scheduled purge yet.
  • Transport is TLS on this host.
  • Harbour does not lodge SuperStream, does not take payroll credentials, and does not see payment cards.
