Egbert stores the minimum data needed to operate an account, support onboarding, and monitor system health. Broker credentials are encrypted before they are persisted.
Account usernames, email addresses, broker selections, onboarding state, and operational audit events are retained so the product can authenticate users, route onboarding, and explain what happened later.
The public site is not positioned as anonymous browsing once you create an account. If you are only evaluating the product, use the public demo before sharing any broker credentials.
