Security
Every client, calculator and document belongs to one organization. The database itself refuses access across organizations.
Row-level security checks every request. Only active members see data, and suspended members lose access immediately.
Owners and admins manage the team and decide who may edit organization details, send invitations or view activity.
Email confirmation, leaked-password screening, and authenticator-app two-step verification support.
Logos and documents are stored privately and shown only through short-lived signed links.
Key changes are recorded automatically and cannot be edited or erased from the app.
Exported results are recalculated on the server and saved as immutable snapshots with rule and table versions.
Scenarios and documents are soft-deleted first, so accidental removals can be reviewed before permanent purge.
