3. Data storage & security

Each client's data is stored in an isolated Neon Postgres database. We use encryption at rest and in transit. API keys are stored as SHA-256 hashes. JWT sessions expire after 7 days.

Enterprise clients receive their own dedicated database instance. No data is shared between clients. Demo data is stored separately in a shared demo environment.
