Enterprise-grade security
Your inventory, completely private.
Google OAuth or generated credentials - no public sign-up. Every account requires your explicit invitation.
Session tokens tied to a single device. Revoke access instantly from the admin panel - the user is signed out immediately.
Role-based permissions let you share curated gem shows with clients while keeping cost prices and internal notes hidden.
Every account is verified by email, and signing in from a new device asks for a fresh emailed code - so a stolen password alone is never enough.
Encrypted off-site backups, plus a full export you can download and restore any time - your data is never locked in.
